3 | New Features in Exim | |
4 | -------------------- | |
5 | ||
38a0a95f PH |
6 | This file contains descriptions of new features that have been added to Exim. |
7 | Before a formal release, there may be quite a lot of detail so that people can | |
8 | test from the snapshots or the CVS before the documentation is updated. Once | |
9 | the documentation is updated, this file is reduced to a short list. | |
10 | ||
b4ed4da0 PH |
11 | Version 4.67 |
12 | ------------ | |
13 | ||
14 | 1. There is a new log selector called smtp_no_mail, which is not included in | |
15 | the default setting. When it is set, a line is written to the main log | |
16 | whenever an accepted SMTP connection terminates without having issued a | |
17 | MAIL command. This includes both the case when the connection is dropped, | |
18 | and the case when QUIT is used. Note that it does not include cases where | |
19 | the connection is rejected right at the start (by an ACL, or because there | |
20 | are too many connections, or whatever). These cases already have their own | |
21 | log lines. | |
22 | ||
23 | The log line that is written contains the identity of the client in the | |
24 | usual way, followed by D= and a time, which records the duration of the | |
25 | connection. If the connection was authenticated, this fact is logged | |
26 | exactly as it is for an incoming message, with an A= item. If the | |
27 | connection was encrypted, CV=, DN=, and X= items may appear as they do for | |
28 | an incoming message, controlled by the same logging options. | |
29 | ||
30 | Finally, if any SMTP commands were issued during the connection, a C= item | |
31 | is added to the line, listing the commands that were used. For example, | |
32 | ||
33 | C=EHLO,QUIT | |
34 | ||
35 | shows that the client issued QUIT straight after EHLO. If there were fewer | |
36 | than 20 commands, they are all listed. If there were more than 20 commands, | |
37 | the last 20 are listed, preceded by "...". However, with the default | |
38 | setting of 10 for smtp_accep_max_nonmail, the connection will in any case | |
39 | be aborted before 20 non-mail commands are processed. | |
40 | ||
41 | ||
42 | Version 4.66 | |
43 | ------------ | |
44 | ||
45 | No new features were added to 4.66. | |
46 | ||
47 | ||
48 | Version 4.65 | |
49 | ------------ | |
50 | ||
51 | No new features were added to 4.65. | |
52 | ||
38a0a95f PH |
53 | |
54 | Version 4.64 | |
55 | ------------ | |
56 | ||

57 | 1. ACL variables can now be given arbitrary names, as long as they start with |
58 | "acl_c" or "acl_m" (for connection variables and message variables), are at | |
59 | least six characters long, with the sixth character being either a digit or | |
883335dc | 60 | an underscore. |
af561417 PH |
61 | |
62 | 2. There is a new ACL modifier called log_reject_target. It makes it possible | |
883335dc | 63 | to specify which logs are used for messages about ACL rejections. |
af561417 PH |
64 | |
65 | 3. There is a new authenticator called "dovecot". This is an interface to the | |
66 | authentication facility of the Dovecot POP/IMAP server, which can support a | |
883335dc | 67 | number of authentication methods. |
af561417 PH |
68 | |
69 | 4. The variable $message_headers_raw provides a concatenation of all the | |
70 | messages's headers without any decoding. This is in contrast to | |
71 | $message_headers, which does RFC2047 decoding on the header contents. | |
72 | ||
883335dc PH |
73 | 5. In a DNS black list, if two domain names, comma-separated, are given, the |
74 | second is used first to do an initial check, making use of any IP value | |
75 | restrictions that are set. If there is a match, the first domain is used, | |
76 | without any IP value restrictions, to get the TXT record. | |
af561417 | 77 | |
883335dc | 78 | 6. All authenticators now have a server_condition option. |
af561417 PH |
79 | |
80 | 7. There is a new command-line option called -Mset. It is useful only in | |
81 | conjunction with -be (that is, when testing string expansions). It must be | |
82 | followed by a message id; Exim loads the given message from its spool | |
883335dc | 83 | before doing the expansions. |
af561417 PH |
84 | |
85 | 8. Another similar new command-line option is called -bem. It operates like | |
883335dc PH |
86 | -be except that it must be followed by the name of a file that contains a |
87 | message. | |
af561417 PH |
88 | |
89 | 9. When an address is delayed because of a 4xx response to a RCPT command, it | |
90 | is now the combination of sender and recipient that is delayed in | |
883335dc | 91 | subsequent queue runs until its retry time is reached. |
af561417 PH |
92 | |
93 | 10. Unary negation and the bitwise logical operators and, or, xor, not, and | |
883335dc | 94 | shift, have been added to the eval: and eval10: expansion items. |
48c7f9e2 | 95 | |
194cc0e4 PH |
96 | 11. The variables $interface_address and $interface_port have been renamed |
97 | as $received_ip_address and $received_port, to make it clear that they | |
98 | relate to message reception rather than delivery. (The old names remain | |
99 | available for compatibility.) | |
100 | ||
883335dc PH |
101 | 12. The "message" modifier can now be used on "accept" and "discard" acl verbs |
102 | to vary the message that is sent when an SMTP command is accepted. | |
4e88a19f | 103 | |
495ae4b0 | 104 | |
4608d683 PH |
105 | Version 4.63 |
106 | ------------ | |
107 | ||
108 | 1. There is a new Boolean option called filter_prepend_home for the redirect | |
38a0a95f | 109 | router. |
4608d683 | 110 | |
45b91596 PH |
111 | 2. There is a new acl, set by acl_not_smtp_start, which is run right at the |
112 | start of receiving a non-SMTP message, before any of the message has been | |
38a0a95f | 113 | read. |
45b91596 | 114 | |
a5bd321b PH |
115 | 3. When an SMTP error message is specified in a "message" modifier in an ACL, |
116 | or in a :fail: or :defer: message in a redirect router, Exim now checks the | |
38a0a95f | 117 | start of the message for an SMTP error code. |
a5bd321b | 118 | |
6ec97b1b | 119 | 4. There is a new parameter for LDAP lookups called "referrals", which takes |
38a0a95f | 120 | one of the settings "follow" (the default) or "nofollow". |
6ec97b1b | 121 | |
e22ca4ac JJ |
122 | 5. Version 20070721.2 of exipick now included, offering these new options: |
123 | --reverse | |
124 | After all other sorting options have bee processed, reverse order | |
125 | before displaying messages (-R is synonym). | |
126 | --random | |
127 | Randomize order of matching messages before displaying. | |
128 | --size | |
129 | Instead of displaying the matching messages, display the sum | |
130 | of their sizes. | |
131 | --sort <variable>[,<variable>...] | |
132 | Before displaying matching messages, sort the messages according to | |
133 | each messages value for each variable. | |
134 | --not | |
135 | Negate the value for every test (returns inverse output from the | |
136 | same criteria without --not). | |
137 | ||
4608d683 | 138 | |
1cce3af8 PH |
139 | Version 4.62 |
140 | ------------ | |
141 | ||
142 | 1. The ${readsocket expansion item now supports Internet domain sockets as well | |
143 | as Unix domain sockets. If the first argument begins "inet:", it must be of | |
144 | the form "inet:host:port". The port is mandatory; it may be a number or the | |
145 | name of a TCP port in /etc/services. The host may be a name, or it may be an | |
146 | IP address. An ip address may optionally be enclosed in square brackets. | |
147 | This is best for IPv6 addresses. For example: | |
148 | ||
149 | ${readsocket{inet:[::1]:1234}{<request data>}... | |
150 | ||
151 | Only a single host name may be given, but if looking it up yield more than | |
152 | one IP address, they are each tried in turn until a connection is made. Once | |
153 | a connection has been made, the behaviour is as for ${readsocket with a Unix | |
154 | domain socket. | |
155 | ||
f7fd3850 PH |
156 | 2. If a redirect router sets up file or pipe deliveries for more than one |
157 | incoming address, and the relevant transport has batch_max set greater than | |
158 | one, a batch delivery now occurs. | |
159 | ||
d6629cdc PH |
160 | 3. The appendfile transport has a new option called maildirfolder_create_regex. |
161 | Its value is a regular expression. For a maildir delivery, this is matched | |
162 | against the maildir directory; if it matches, Exim ensures that a | |
163 | maildirfolder file is created alongside the new, cur, and tmp directories. | |
164 | ||
1cce3af8 | 165 | |
7e66e54d PH |
166 | Version 4.61 |
167 | ------------ | |
168 | ||
4f578862 PH |
169 | The documentation is up-to-date for the 4.61 release. Major new features since |
170 | the 4.60 release are: | |
171 | ||
172 | . An option called disable_ipv6, to disable the use of IPv6 completely. | |
173 | ||
174 | . An increase in the number of ACL variables to 20 of each type. | |
175 | ||
176 | . A change to use $auth1, $auth2, and $auth3 in authenticators instead of $1, | |
177 | $2, $3, (though those are still set) because the numeric variables get used | |
178 | for other things in complicated expansions. | |
179 | ||
843a41e8 | 180 | . The default for rfc1413_query_timeout has been changed from 30s to 5s. |
4f578862 PH |
181 | |
182 | . It is possible to use setclassresources() on some BSD OS to control the | |
183 | resources used in pipe deliveries. | |
184 | ||
185 | . A new ACL modifier called add_header, which can be used with any verb. | |
186 | ||
187 | . More errors are detectable in retry rules. | |
188 | ||
189 | There are a number of other additions too. | |

b5aea5e1 | 209 | |
425ae40f | 210 | . A "match_ip" condition, that matches an IP address against a list. |
35edf2ff | 211 | |
425ae40f | 212 | There are many more minor changes. |
