6JH/01 Use SIZE on MAIL FROM in a cutthrough connection, if the destination
7 supports it and a size is available (ie. the sending peer gave us one).
8d042305 8
03d5892b
JH
9JH/02 The obsolete acl condition "demime" is removed (finally, after ten
10 years of being deprecated). The replacements are the ACLs
11 acl_smtp_mime and acl_not_smtp_mime.
12
4b0fe319
JH
13JH/03 Upgrade security requirements imposed for hosts_try_dane: previously
14 a downgraded non-dane trust-anchor for the TLS connection (CA-style)
15 or even an in-clear connection were permitted. Now, if the host lookup
16 was dnssec and dane was requested then the host is only used if the
17 TLSA lookup succeeds and is dnssec. Further hosts (eg. lower priority
18 MXs) will be tried (for hosts_try_dane though not for hosts_require_dane)
19 if one fails this test.
20 This means that a poorly-configured remote DNS will make it incommunicado;
21 but it protects against a DNS-interception attack on it.

23JH/04 Bug 1810: make continued-use of an open smtp transport connection
24 non-noisy when a race steals the message being considered.

JH
26JH/05 If main configuration option tls_certificate is unset, generate a
27 selfsigned certificate for inbound TLS connections.
28
0bd1b1ed 29JH/06 Bug 165: hide more cases of password exposure - this time in expansions
f42deca9 30 in rewrites and routers.
0bd1b1ed 31
20b9a2dc
JH
32JH/07 Retire gnutls_require_mac et.al. These were nonfunctional since 4.80
33 and logged a warning sing 4.83; now they are a configuration file error.
34
05392bbc
JH
35JH/08 Bug 1836: Fix crash in VRFY handling when handed an unqualified name
36 (lacking @domain). Apply the same qualification processing as RCPT.
37
1a6230a3
JH
38JH/09 Bug 1804: Avoid writing msglog files when in -bh or -bhc mode.
39
cfab9d68
JH
40JH/10 Support ${sha256:} applied to a string (as well as the previous
41 certificate).
42
98c82a3d
JH
43JH/11 Cutthrough: avoid using the callout hints db on a verify callout when
44 a cutthrough deliver is pending, as we always want to make a connection.
45 This also avoids re-routing the message when later placing the cutthrough
46 connection after a verify cache hit.
47 Do not update it with the verify result either.
48
49JH/12 Cutthrough: disable when verify option success_on_redirect is used, and
50 when routing results in more than one destination address.
51
ae8386f0
JH
52JH/13 Cutthrough: expand transport dkim_domain option when testing for dkim
53 signing (which inhibits the cutthrough capability). Previously only
54 the presence of an option was tested; now an expansion evaluating as
55 empty is permissible (obviously it should depend only on data available
56 when the cutthrough connection is made).
57
0d9fa8c0
JH
58JH/14 Fix logging of errors under PIPELINING. Previously the log line giving
59 the relevant preceding SMTP command did not note the pipelining mode.
60
3581f321
JH
61JH/15 Fix counting of empty lines in $body_linecount and $message_linecount.
62 Previously they were not counted.
63
ef3a1a30
JH
64JH/16 DANE: treat a TLSA lookup response having all non-TLSA RRs, the same
65 as one having no matching records. Previously we deferred the message
66 that needed the lookup.
67
803628d5 68JH/17 Fakereject: previously logged as a norml message arrival "<="; now

JH
71JH/18 Bug 1867: make the fail_defer_domains option on a dnslookup router work
72 for missing MX records. Previously it only worked for missing A records.

JB
74JH/19 Bug 1850: support Radius libraries that return REJECT_RC.
75
76JH/20 Bug 1872: Ensure that acl_smtp_notquit is run when the connection drops
77 after the data-go-ahead and data-ack. Patch from Jason Betts.

83Exim version 4.87
84-----------------
82d14d6a
JH
85JH/01 Bug 1664: Disable OCSP for GnuTLS library versions at/before 3.3.16
86 and 3.4.4 - once the server is enabled to respond to an OCSP request
87 it does even when not requested, resulting in a stapling non-aware
88 client dropping the TLS connection.

TF
90TF/01 Code cleanup: Overhaul the debug_selector and log_selector machinery to
91 support variable-length bit vectors. No functional change.
92
ac881e27
TF
93TF/02 Improve the consistency of logging incoming and outgoing interfaces.
94 The I= interface field on outgoing lines is now after the H= remote
95 host field, same as incoming lines. There is a separate
96 outgoing_interface log selector which allows you to disable the
97 outgoing I= field.
98
c8899c20
JH
99JH/02 Bug 728: Close logfiles after a daemon-process "exceptional" log write.
100 If not running log_selector +smtp_connection the mainlog would be held
101 open indefinitely after a "too many connections" event, including to a
102 deleted file after a log rotate. Leave the per net connection logging
103 leaving it open for efficiency as that will be quickly detected by the
104 check on the next write.
105
f1b81d81
HSHR
106HS/01 Bug 1671: Fix post transport crash.
107 Processing the wait-<transport> messages could crash the delivery
108 process if the message IDs didn't exist for some reason. When
109 using 'split_spool_directory=yes' the construction of the spool
110 file name failed already, exposing the same netto behaviour.
111

112JH/03 Bug 425: Capture substrings in $regex1, $regex2 etc from regex &
113 mime_regex ACL conditions.

JH
115JH/04 Bug 1686: When compiled with EXPERIMENTAL_DSN_INFO: Add extra information
116 to DSN fail messages (bounces): remote IP, remote greeting, remote response
117 to HELO, local diagnostic string.
118
805bb5c3
JH
119JH/05 Downgrade message for a TLS-certificate-based authentication fail from
120 log line to debug. Even when configured with a tls authenticator many
121 client connections are expected to not authenticate in this way, so
122 an authenticate fail is not an error.
123
56c2a7be
HSHR
124HS/02 Add the Exim version string to the process info. This way exiwhat
125 gives some more detail about the running daemon.
126
14b3c5bc
JH
127JH/06 Bug 1395: time-limit cacheing of DNS lookups, to the TTL value. This may
128 matter for fast-change records such as DNSBLs.
129
6f6dedcc
JH
130JH/07 Bug 1678: Always record an interface option value, if set, as part of a
131 retry record, even if constant. There may be multiple transports with
132 different interface settings and the retry behaviour needs to be kept
133 distinct.
134
0f557e90
JH
135JH/08 Bug 1586: exiqgrep now refuses to run if there are unexpected arguments.
136
137JH/09 Bug 1700: ignore space & tab embedded in base64 during decode.
138

JH
139JH/10 Bug 840: fix log_defer_output option of pipe transport
140
41e93589
JH
141JH/11 Bug 830: use same host for all RCPTS of a message, even under
142 hosts_randomize. This matters a lot when combined with mua_wrapper.
143
98b98887 144JH/12 Bug 1706: percent and underbar characters are no longer escaped by the
376d2ec0
JH
145 ${quote_pgsql:<string>} operator.
146
98b98887
JH
147JH/13 Bug 1708: avoid misaligned access in cached lookup.
148
858e91c2
JH
149JH/14 Change header file name for freeradius-client. Relevant if compiling
150 with Radius support; from the Gentoo tree and checked under Fedora.
151
152JH/15 Bug 1712: Introduce $prdr_requested flag variable
153
6ff55e50
JH
154JH/16 Bug 1714: Permit an empty string as expansion result for transport
155 option transport_filter, meaning no filtering.

JB
157JH/17 Bug 1713: Fix non-PDKIM_DEBUG build. Patch from Jasen Betts.
158
23f3dc67
JH
159JH/18 Bug 1709: When built with TLS support, the tls_advertise_hosts option now
160 defaults to "*" (all hosts). The variable is now available when not built
161 with TLS, default unset, mainly to enable keeping the testuite sane.
162 If a server certificate is not supplied (via tls_certificate) an error is
163 logged, and clients will find TLS connections fail on startup. Presumably
164 they will retry in-clear.
165 Packagers of Exim are strongly encouraged to create a server certificate
166 at installation time.
167
240c288f
JH
168HS/03 Add -bP config_file as a synonym for -bP configure_file, for consistency
169 with the $config_file variable.
170
5ef5dd52
JB
171JH/19 Two additional event types: msg:rcpt:defer and msg:rcpt:host:defer. Both
172 in transport context, after the attempt, and per-recipient. The latter type
173 is per host attempted. The event data is the error message, and the errno
174 information encodes the lookup type (A vs. MX) used for the (first) host,
175 and the trailing two digits of the smtp 4xx reponse.
176
e161710d
GF
177GF/01 Bug 1715: Fix for race condition in exicyclog, where exim could attempt
178 to write to mainlog (or rejectlog, paniclog) in the window between file
179 creation and permissions/ownership being changed. Particularly affects
180 installations where exicyclog is run as root, rather than exim user;
181 result is that the running daemon panics and dies.
182

JH
183JH/20 Bug 1701: For MySQL lookups, support MySQL config file option group names.
184
7f06582c
JH
185JH/21 Bug 1720: Add support for priority groups and weighted-random proxy
186 selection for the EXPERIMENTAL_SOCKS feature, via new per-proxy options
187 "pri" and "weight". Note that the previous implicit priority given by the
188 list order is no longer honoured.

cee5f132
JH
196JH/26 Move PROXY support from Experimental to mainline, enabled for a build
197 by defining SUPPORT_PROXY. Note that the proxy_required_hosts option
e6d2a989
JH
198 is renamed to hosts_proxy, and the proxy_{host,target}_{address,port}.
199 variables are renamed to proxy_{local,external}_{address,port}.

218JH/33 Bug 1748: Permit ACL dnslists= condition in non-smtp ACLs if explicit
219 keys are given for lookup.
220
f444c2c7
JH
221JH/34 Bug 1192: replace the embedded copy of PolarSSL RSA routines in the DKIM
222 support, by using OpenSSL or GnuTLS library ones. This means DKIM is
07c73177
JH
223 only supported when built with TLS support. The PolarSSL SHA routines
224 are still used when the TLS library is too old for convenient support.
f444c2c7 225
a57b6200
JH
226JH/35 Require SINGLE_DH_USE by default in OpenSSL (main config option
227 openssl_options), for security. OpenSSL forces this from version 1.1.0
228 server-side so match that on older versions.
229
07c73177 230JH/36 Bug 1778: longstanding bug in memory use by the ${run } expansion: A fresh
fa01e4f8 231 allocation for $value could be released as the expansion processing
07c73177 232 concluded, but leaving the global pointer active for it.
fa01e4f8 233
4f6ae5c3
JH
234JH/37 Bug 1769: Permit a VRFY ACL to override the default 252 response,
235 and to use the domains and local_parts ACL conditions.
236
1bc460a6
JH
237JH/38 Fix cutthrough bug with body lines having a single dot. The dot was
238 incorrectly not doubled on cutthrough transmission, hence seen as a
239 body-termination at the receiving system - resulting in truncated mails.
62ac2eb7 240 Commonly the sender saw a TCP-level error, and retransmitted the message
1bc460a6
JH
241 via the normal store-and-forward channel. This could result in duplicates
242 received - but deduplicating mailstores were liable to retain only the
243 initial truncated version.

JH
256JH/43 Tidy coding issues detected by gcc --fsanitize=undefined. Some remain;
257 either intentional arithmetic overflow during PRNG, or testing config-
258 induced overflows.
259

JH
260JH/44 Bug 1800: The combination of a -bhc commandline option and cutthrough
261 delivery resulted in actual delivery. Cancel cutthrough before DATA
262 stage.
263
f9334a28
JH
264JH/45 Fix cutthrough, when connection not opened by verify and target hard-
265 rejects a recipient: pass the reject to the originator.
266
dc8091e7
JH
267JH/46 Multiple issues raised by Coverity. Some were obvious or plausible bugs.
268 Many were false-positives and ignorable, but it's worth fixing the
269 former class.
270
dfe7d917
JH
271JH/47 Fix build on HP-UX and older Solaris, which need (un)setenv now also
272 for the new environment-manipulation done at startup. Move the routines
273 from being local to tls.c to being global via the os.c file.
274
93cc2d6e
JH
275JH/48 Bug 1807: Fix ${extract } for the numeric/3-string case. While preparsing
276 an extract embedded as result-arg for a map, the first arg for extract
277 is unavailable so we cannot tell if this is a numbered or keyed
278 extraction. Accept either.

377 Normally benign, it bites when the pair was led to by a CNAME;

406TL/01 When running the test suite, the README says that variables such as
407 no_msglog_check are global and can be placed anywhere in a specific
408 test's script, however it was observed that placement needed to be near
409 the beginning for it to behave that way. Changed the runtest perl
410 script to read through the entire script once to detect and set these
411 variables, reset to the beginning of the script, and then run through
412 the script parsing/test process like normal.

769TF/01 Fix ultimate retry timeouts for intermittently deliverable recipients.
770
771 When a queue runner is handling a message, Exim first routes the
772 recipient addresses, during which it prunes them based on the retry
773 hints database. After that it attempts to deliver the message to
774 any remaining recipients. It then updates the hints database using
775 the retry rules.
776
777 So if a recipient address works intermittently, it can get repeatedly
778 deferred at routing time. The retry hints record remains fresh so the
779 address never reaches the final cutoff time.
780
781 This is a fairly common occurrence when a user is bumping up against
782 their storage quota. Exim had some logic in its local delivery code
783 to deal with this. However it did not apply to per-recipient defers
784 in remote deliveries, e.g. over LMTP to a separate IMAP message store.
785
1ddeb334
TF
786 This change adds a proper retry rule check during routing so that the
787 final cutoff time is checked against the message's age. We only do
788 this check if there is an address retry record and there is not a
789 domain retry record; this implies that previous attempts to handle
790 the address had the retry_use_local_parts option turned on. We use
791 this as an approximation for the destination being like a local
792 delivery, as in LMTP.

802
803 When I ran the test suite under the user fanf2, Exim expanded
804 the header to contain my full name, whereas it should have added
805 a Resent-Sender: header. It erroneously treats any prefix of the
806 username as equal to the username.

830 Server implementation by Todd Lyons, client by JH.
831 Only enabled when compiled with EXPERIMENTAL_PRDR. A new
832 config variable "prdr_enable" controls whether the server
833 advertises the facility. If the client requests PRDR a new
834 acl_data_smtp_prdr ACL is called once for each recipient, after
835 the body content is received and before the acl_smtp_data ACL.
836 The client is controlled by bolth of: a hosts_try_prdr option
837 on the smtp transport, and the server advertisement.
838 Default client logging of deliveries and rejections involving
839 PRDR are flagged with the string "PRDR".

1117TF/03 Make the exiwhat support code safe for signals. Previously Exim might
1118 lock up or crash if it happened to be inside a call to libc when it
1119 got a SIGUSR1 from exiwhat.
1120
1121 The SIGUSR1 handler appends the current process status to the process
1122 log which is later printed by exiwhat. It used to use the general
1123 purpose logging code to do this, but several functions it calls are
1124 not safe for signals.
1125
1126 The new output code in the SIGUSR1 handler is specific to the process
1127 log, and simple enough that it's easy to inspect for signal safety.
1128 Removing some special cases also simplifies the general logging code.
1129 Removing the spurious timestamps from the process log simplifies
1130 exiwhat.

TF
1132TF/04 Improved ratelimit ACL condition.
1133
1134 The /noupdate option has been deprecated in favour of /readonly which
1135 has clearer semantics. The /leaky, /strict, and /readonly update modes
1136 are mutually exclusive. The update mode is no longer included in the
1137 database key; it just determines when the database is updated. (This
1138 means that when you upgrde Exim will forget old rate measurements.)
1139
1140 Exim now checks that the per_* options are used with an update mode that
1141 makes sense for the current ACL. For example, when Exim is processing a
1142 message (e.g. acl_smtp_rcpt or acl_smtp_data, etc.) you can specify
1143 per_mail/leaky or per_mail/strict; otherwise (e.g. in acl_smtp_helo) you
1144 must specify per_mail/readonly. If you omit the update mode it defaults to
1145 /leaky where that makes sense (as before) or /readonly where required.
1146
1147 The /noupdate option is now undocumented but still supported for
1148 backwards compatibility. It is equivalent to /readonly except that in
1149 ACLs where /readonly is required you may specify /leaky/noupdate or
1150 /strict/noupdate which are treated the same as /readonly.
1151
1152 A useful new feature is the /count= option. This is a generalization
1153 of the per_byte option, so that you can measure the throughput of other
1154 aggregate values. For example, the per_byte option is now equivalent
1155 to per_mail/count=${if >{0}{$message_size} {0} {$message_size} }.
1156
1157 The per_rcpt option has been generalized using the /count= mechanism
1158 (though it's more complicated than the per_byte equivalence). When it is
1159 used in acl_smtp_rcpt, the per_rcpt option adds recipients to the
1160 measured rate one at a time; if it is used later (e.g. in acl_smtp_data)
1161 or in a non-SMTP ACL it adds all the recipients in one go. (The latter
1162 /count=$recipients_count behaviour used to work only in non-SMTP ACLs.)
1163 Note that using per_rcpt with a non-readonly update mode in more than
1164 one ACL will cause the recipients to be double-counted. (The per_mail
1165 and per_byte options don't have this problem.)
1166
1167 The handling of very low rates has changed slightly. If the computed rate
1168 is less than the event's count (usually one) then this event is the first
1169 after a long gap. In this case the rate is set to the same as this event's
1170 count, so that the first message of a spam run is counted properly.
1171
1172 The major new feature is a mechanism for counting the rate of unique
1173 events. The new per_addr option counts the number of different
1174 recipients that someone has sent messages to in the last time period. It
1175 behaves like per_rcpt if all the recipient addresses are different, but
1176 duplicate recipient addresses do not increase the measured rate. Like
1177 the /count= option this is a general mechanism, so the per_addr option
1178 is equivalent to per_rcpt/unique=$local_part@$domain. You can, for
1179 example, measure the rate that a client uses different sender addresses
1180 with the options per_mail/unique=$sender_address. There are further
1181 details in the main documentation.

1751-----------------
1752
1753PH/01 Another patch from the Sieve maintainer.
1754
6a3bceb1
PH
1755PH/02 When an IPv6 address is converted to a string for single-key lookup
1756 in an address list (e.g. for an item such as "net24-dbm;/net/works"),
1757 dots are used instead of colons so that keys in lsearch files need not
1758 contain colons. This was done some time before quoting was made available
1759 in lsearch files. However, iplsearch files do require colons in IPv6 keys
1760 (notated using the quote facility) so as to distinguish them from IPv4
1761 keys. This meant that lookups for IP addresses in host lists did not work
1762 for iplsearch lookups.
1763
1764 This has been fixed by arranging for IPv6 addresses to be expressed with
1765 colons if the lookup type is iplsearch. This is not incompatible, because
1766 previously such lookups could never work.
1767
1768 The situation is now rather anomolous, since one *can* have colons in
1769 ordinary lsearch keys. However, making the change in all cases is
1770 incompatible and would probably break a number of configurations.

1775MH/01 The "spam" ACL condition code contained a sscanf() call with a %s
1776 conversion specification without a maximum field width, thereby enabling
1777 a rogue spamd server to cause a buffer overflow. While nobody in their
1778 right mind would setup Exim to query an untrusted spamd server, an
1779 attacker that gains access to a server running spamd could potentially
1780 exploit this vulnerability to run arbitrary code as the Exim user.

MH
1785MH/02 The dsearch lookup now uses lstat(2) instead of stat(2) to look for
1786 a directory entry by the name of the lookup key. Previously, if a
1787 symlink pointed to a non-existing file or a file in a directory that
1788 Exim lacked permissions to read, a lookup for a key matching that
1789 symlink would fail. Now it is enough that a matching directory entry
1790 exists, symlink or not. (Bugzilla 503.)

1973PH/29 SMTP synchronization checks are implemented when a command is read -
1974 there is a check that no more input is waiting when there shouldn't be
1975 any. However, for some commands, a delay in an ACL can mean that it is
1976 some time before the response is written. In this time, more input might
1977 arrive, invalidly. So now there are extra checks after an ACL has run for
1978 HELO/EHLO and after the predata ACL, and likewise for MAIL and RCPT when
1979 pipelining has not been advertised.

PH
2053 the response to the final '.' that terminates a message, but only in the
2054 case where the client has not sent further data following the '.'
2055 (unfortunately, this is allowed). However, in many cases there won't be
2056 any further data because there won't be any more messages to send. A call
2057 to select() can be used: if it shows that the input is "ready", there is
2058 either input waiting, or the socket has been closed. An attempt to read
2059 the next input character can distinguish the two cases. Previously, Exim
58eb016e 2060 would have sent an OK response which the client would never have see.

2071PH/01 Two more bugs that were introduced by 4.64/PH/07, in addition to the one
2072 fixed by 4.65/MH/01 (is this a record?) are fixed:
2073
2074 (i) An empty string was always treated as zero by the numeric comparison
2075 operators. This behaviour has been restored.
2076
2077 (ii) It is documented that the numeric comparison operators always treat
2078 their arguments as decimal numbers. This was broken in that numbers
2079 starting with 0 were being interpreted as octal.
2080
2081 While fixing these problems I realized that there was another issue that
2082 hadn't been noticed. Values of message_size_limit (both the global option
2083 and the transport option) were treated as octal if they started with 0.
2084 The documentation was vague. These values are now always treated as
2085 decimal, and I will make that clear in the documentation.

2102 large number of recipients for a single message is ridiculous
2103 (performance will be very, very poor), I have chosen to impose a limit
2104 rather than extend the field.

PH
2129PH/01 If a server that rejects MAIL FROM:<> was the target of a sender
2130 callout verification, Exim cached a "reject" for the entire domain. This
2131 is correct for most verifications, but it is not correct for a recipient
2132 verification with use_sender or use_postmaster set, because in that case
2133 the callout does not use MAIL FROM:<>. Exim now distinguishes the special
2134 case of MAIL FROM:<> rejection from other early rejections (e.g.
2135 rejection of HELO). When verifying a recipient using a non-null MAIL
2136 address, the cache is ignored if it shows MAIL FROM:<> rejection.
2137 Whatever the result of the callout, the value of the domain cache is
2138 left unchanged (for any other kind of callout, getting as far as trying
2139 RCPT means that the domain itself is ok).

2173PH/11 Callouts were setting the name used for EHLO/HELO from $smtp_active_
2174 hostname. This is wrong, because it relates to the incoming message (and
2175 probably the interface on which it is arriving) and not to the outgoing
2176 callout (which could be using a different interface). This has been
2177 changed to use the value of the helo_data option from the smtp transport
2178 instead - this is what is used when a message is actually being sent. If
2179 there is no remote transport (possible with a router that sets up host
2180 addresses), $smtp_active_hostname is used.

7befa435 2183 tweaks were necessary in order to get it to work (see also 21 below):
14aa5a05
PH
2184 (a) The code assumed that strncpy() returns a negative number on buffer
2185 overflow, which isn't the case. Replaced with Exim's string_format()
2186 function.
2187 (b) There were several signed/unsigned issues. I just did the minimum
2188 hacking in of casts. There is scope for a larger refactoring.
2189 (c) The code used strcasecmp() which is not a standard C function.
2190 Replaced with Exim's strcmpic() function.
2191 (d) The code set only $1; it now sets $auth1 as well.
2192 (e) A simple test gave the error "authentication client didn't specify
2193 service in request". It would seem that Dovecot has changed its
2194 interface. Fortunately there's a specification; I followed it and
2195 changed what the client sends and it appears to be working now.

2200PH/14 Corrected misleading output from -bv when -v was also used. Suppose the
2201 address A is aliased to B and C, where B exists and C does not. Without
2202 -v the output is "A verified" because verification stops after a
2203 successful redirection if more than one address is generated. However,
2204 with -v the child addresses are also verified. Exim was outputting "A
2205 failed to verify" and then showing the successful verification for C,
2206 with its parentage. It now outputs "B failed to verify", showing B's
2207 parentage before showing the successful verification of C.

2210 look up a TXT record in a specific list after matching in a combined

2212
322050c2
PH
2213PH/16 It seems that the options setting for the resolver (RES_DEFNAMES and
2214 RES_DNSRCH) can affect the behaviour of gethostbyname() and friends when
2215 they consult the DNS. I had assumed they would set it the way they
2216 wanted; and indeed my experiments on Linux seem to show that in some
2217 cases they do (I could influence IPv6 lookups but not IPv4 lookups).
2218 To be on the safe side, however, I have now made the interface to
2219 host_find_byname() similar to host_find_bydns(), with an argument
2220 containing the DNS resolver options. The host_find_byname() function now
2221 sets these options at its start, just as host_find_bydns() does. The smtp
2222 transport options dns_qualify_single and dns_search_parents are passed to
2223 host_find_byname() when gethostbyname=TRUE in this transport. Other uses
2224 of host_find_byname() use the default settings of RES_DEFNAMES
2225 (qualify_single) but not RES_DNSRCH (search_parents).

2227PH/17 Applied (a modified version of) Nico Erfurth's patch to make
2228 spool_read_header() do less string testing, by means of a preliminary
2229 switch on the second character of optional "-foo" lines. (This is
2230 overdue, caused by the large number of possibilities that now exist.
2231 Originally there were few.) While I was there, I also converted the
2232 str(n)cmp tests so they don't re-test the leading "-" and the first
2233 character, in the hope this might squeeze out yet more improvement.

PH
2235PH/18 Two problems with "group" syntax in header lines when verifying: (1) The
2236 flag allowing group syntax was set by the header_syntax check but not
2237 turned off, possible causing trouble later; (2) The flag was not being
2238 set at all for the header_verify test, causing "group"-style headers to
2239 be rejected. I have now set it in this case, and also caused header_
2240 verify to ignore an empty address taken from a group. While doing this, I
2241 came across some other cases where the code for allowing group syntax
2242 while scanning a header line wasn't quite right (mostly, not resetting
2243 the flag correctly in the right place). These bugs could have caused
2244 trouble for malformed header lines. I hope it is now all correct.

602e59e5
PH
2246PH/19 The functions {pwcheck,saslauthd}_verify_password() are always called
2247 with the "reply" argument non-NULL. The code, however (which originally
2248 came from elsewhere) had *some* tests for NULL when it wrote to *reply,
2249 but it didn't always do it. This confused somebody who was copying the
2250 code for some other use. I have removed all the tests.

PH
2252PH/20 It was discovered that the GnuTLS code had support for RSA_EXPORT, a
2253 feature that was used to support insecure browsers during the U.S. crypto
2254 embargo. It requires special client support, and Exim is probably the
2255 only MTA that supported it -- and would never use it because real RSA is
2256 always available. This code has been removed, because it had the bad
2257 effect of slowing Exim down by computing (never used) parameters for the
2258 RSA_EXPORT functionality.

2263 to be base64-encoded). Also added, on Timo's advice, the "secured" option
2264 if the connection is using TLS or if the remote IP is the same as the
2265 local IP, and the "valid-client-cert option" if a client certificate has
2266 been verified.

2297
2298PH/30 Exim was sometimes attempting to deliver messages that had suffered
2299 address errors (4xx response to RCPT) over the same connection as other
2300 messages routed to the same hosts. Such deliveries are always "forced",
2301 so retry times are not inspected. This resulted in far too many retries
2302 for the affected addresses. The effect occurred only when there were more
2303 hosts than the hosts_max_try setting in the smtp transport when it had
2304 the 4xx errors. Those hosts that it had tried were not added to the list
2305 of hosts for which the message was waiting, so if all were tried, there
2306 was no problem. Two fixes have been applied:
2307
2308 (i) If there are any address or message errors in an SMTP delivery, none
2309 of the hosts (tried or untried) are now added to the list of hosts
2310 for which the message is waiting, so the message should not be a
2311 candidate for sending over the same connection that was used for a
2312 successful delivery of some other message. This seems entirely
2313 reasonable: after all the message is NOT "waiting for some host".
2314 This is so "obvious" that I'm not sure why it wasn't done
2315 previously. Hope I haven't missed anything, but it can't do any
2316 harm, as the worst effect is to miss an optimization.
2317
2318 (ii) If, despite (i), such a delivery is accidentally attempted, the
2319 routing retry time is respected, so at least it doesn't keep
2320 hammering the server.

2336 written to the panic log as well as the main log, but it isn't really

2341PH/36 After a 4xx response to a RCPT error, that address was delayed (in queue
2342 runs only) independently of the message's sender address. This meant
2343 that, if the 4xx error was in fact related to the sender, a different
2344 message to the same recipient with a different sender could confuse
2345 things. In particualar, this can happen when sending to a greylisting
2346 server, but other circumstances could also provoke similar problems.
2347 I have changed the default so that the retry time for these errors is now
2348 based a combination of the sender and recipient addresses. This change
2349 can be overridden by setting address_retry_include_sender=false in the
2350 smtp transport.

2621 tcp-wrappers gives "deny", whereas what one would like would be some
2622 kind of temporary error. A kludge has been added to help with this.
2623 Before calling hosts_ctl(), errno is set zero. If the result is "deny", a
2624 554 error is used if errno is still zero or contains ENOENT (which occurs
2625 if either of the /etc/hosts.{allow,deny} files is missing). Otherwise, a

2728PH/14 When a uid/gid is specified for the queryprogram router, it cannot be

2731 non-existent - all you got was a failure to exec. I have made two
2732 changes:
2733
2734 (a) Failures to set uid/gid, the current directory, or a process leader
2735 in a subprocess such as that created by queryprogram now generate
2736 suitable debugging ouput when -d is set.
2737
2738 (b) The queryprogram router detects when it is not running as root,
2739 outputs suitable debugging information if -d is set, and then runs
2740 the subprocess without attempting to change uid/gid.

2745PH/16 As discussed on the list in Nov/Dec: Exim no longer looks at the
2746 additional section of a DNS packet that returns MX or SRV records.
2747 Instead, it always explicitly searches for A/AAAA records. This avoids
2748 major problems that occur when a DNS server includes only records of one
2749 type (A or AAAA) in an MX/SRV packet. A byproduct of this change has
2750 fixed another bug: if SRV records were looked up and the corresponding
2751 address records were *not* found in the additional section, the port
2752 values from the SRV records were lost.

2762PH/19 When calculating a retry time, Exim used to measure the "time since
2763 failure" by looking at the "first failed" field in the retry record. Now
2764 it does not use this if it is later than than the arrival time of the
2765 message. Instead it uses the arrival time. This makes for better
2766 behaviour in cases where some deliveries succeed, thus re-setting the
2767 "first failed" field. An example is a quota failure for a huge message
2768 when small messages continue to be delivered. Without this change, the
2769 "time since failure" will always be short, possible causing more frequent
2770 delivery attempts for the huge message than are intended.

2867PH/42 The content-scanning code uses fopen() to create files in which to put
2868 message data. Previously it was not paying any attention to the mode of
2869 the files. Exim runs with umask(0) because the rest of the code creates
2870 files with open(), and sets the required mode explicitly. Thus, these
2871 files were ending up world-writeable. This was not a big issue, because,
2872 being within the spool directory, they were not world-accessible. I have
2873 created a function called modefopen, which takes an additional mode
2874 argument. It sets umask(777), creates the file, chmods it to the required
2875 mode, then resets the umask. All the relevant calls to fopen() in the
2876 content scanning code have been changed to use this function.

2913
2914 (i) Exim was not creating retry information for temporary errors given
2915 for individual recipients after the DATA command when the smtp transport
2916 was used in LMTP mode. This meant that they could be retried too
2917 frequently, and not timed out correctly.
2918
2919 (ii) Exim was setting the flag that allows error details to be returned
2920 for LMTP errors on RCPT commands, but not for LMTP errors for individual
2921 recipients that were returned after the DATA command.
2922
2923PH/53 This is related to PH/52, but is more general: for any failing address,
2924 when detailed error information was permitted to be returned to the
2925 sender, but the error was temporary, then after the final timeout, only
2926 "retry timeout exceeded" was returned. Now it returns the full error as

2998 function verify_get_ident() calls ip_connect() to connect a socket, but
2999 if the "connect()" function timed out, ip_connect() used to close the
3000 socket. However, verify_get_ident() also closes the socket later, and in
3001 between Exim writes to the log, which may get opened at this point. When
3002 the socket was closed in ip_connect(), the log could get the same file
3003 descriptor number as the socket. This naturally causes chaos. The fix is
3004 not to close the socket in ip_connect(); the socket should be closed by
3005 the function that creates it. There was only one place in the code where
3006 this was missing, in the iplookup router, which I don't think anybody now
3007 uses, but I've fixed it anyway.

3068
3069 Received: from [1.2.3.4] (helo=[1.2.3.4])

3137PH/14 Add check_rfc2047_length to disable enforcement of RFC 2047 length

3141PH/15 If the first argument of "${if match_address" was not empty, but did not
3142 contain an "@" character, Exim crashed. Now it writes a panic log message

3147PH/17 A further patch from the Sieve maintainer: "Introduce the new Sieve
3148 extension "envelope-auth". The code is finished and in agreement with
3149 other implementations, but there is no documentation so far and in fact,
3150 nobody wrote the draft yet. This extension is currently #undef'ed, thus
3151 not changing the active code.
3152
3153 Print executed "if" and "elsif" statements when debugging is used. This
3154 helps a great deal to understand what a filter does.
3155
3156 Document more things not specified clearly in RFC3028. I had all this
3157 sorted out, when out of a sudden new issues came to my mind. Oops."

PH
3162PH/19 Exim expands the IPv6 address given to -bh to its full non-abbreviated
3163 canonical form (as documented). However, after a host name lookup from
3164 the IP address, check_host() was doing a simple string comparison with
3165 addresses acquired from the DNS when checking that the found name did
3166 have the original IP as one of its addresses. Since any found IPv6
3167 addresses are likely to be in abbreviated form, the comparison could
3168 fail. Luckily, there already exists a function for doing the comparison
3169 by converting both addresses to binary, so now that is used instead of
3170 the text comparison.
3171
96776534
PH
3172PH/20 There was another similar case to PH/19, when a complete host name was
3173 given in a host list; looking up its IP address could give an abbreviated
3174 form, whereas the current host's name might or might not be abbreviated.
3175 The same fix has been applied.

3190PH/04 Tighten up "personal" tests: Instead of testing for any "List-"
3191 header line, restrict the check to what is listed in RFCs 2369 and 2929.
3192 Also, for "Auto-Submitted", treat anything other than "no" as
3193 non-personal, in accordance with RFC 3834. (Previously it treated
3194 anything starting "auto-" as non-personal.)

3196TF/01 The control=submission/name=... option had a problem with syntax
3197 errors if the name included a slash character. The /name= option
3198 now slurps the rest of the string, so it can include any characters
3199 but it must come last in the list of options (after /sender_retain
3200 or /domain=).

3217PH/03 When creating an mbox file for a virus/spam scan, use fseek() instead of

3249PH/12 There was a missing call to search_tidyup() before the fork() in rda.c to
3250 run a filter in a subprocess. This could lead to confusion in subsequent
3251 lookups in the parent process. There should also be a search_tidyup() at
3252 the end of the subprocess.

3254PH/13 Previously, if "verify = helo" was set in an ACL, the condition was true
3255 only if the host matched helo_try_verify_hosts, which caused the
3256 verification to occur when the EHLO/HELO command was issued. The ACL just
3257 tested the remembered result. Now, if a previous verification attempt has
3258 not happened, "verify = helo" does it there and then.

3287PH/23 Applied a patch to fix problems with exim-4.52 while doing radius
3288 authentication with radiusclient 0.4.9:
3289
3290 - Error returned from rc_read_config was caught wrongly
3291 - Username/password not passed on to radius server due to wrong length.
3292
3293 The presumption is that some radiusclient API changes for 4.51/PH/17
3294 were not taken care of correctly. The code is still untested by me (my
3295 Linux distribution still has 0.3.2 of radiusclient), but it was
3296 contributed by a Radius user.

3311PH/26 Exim was recognizing IPv6 addresses of the form [IPv6:....] in EHLO

3318PH/28 Exim tries to create and chdir to its spool directory when it starts;
