The doc/ChangeLog file contains a listing of all changes, including bug fixes. +Version 4.62 +------------ + +1. The ${readsocket expansion item now supports Internet domain sockets as well + as Unix domain sockets. If the first argument begins "inet:", it must be of + the form "inet:host:port". The port is mandatory; it may be a number or the + name of a TCP port in /etc/services. The host may be a name, or it may be an + IP address. An ip address may optionally be enclosed in square brackets. + This is best for IPv6 addresses. For example: + + ${readsocket{inet:[::1]:1234}{}... + + Only a single host name may be given, but if looking it up yield more than + one IP address, they are each tried in turn until a connection is made. Once + a connection has been made, the behaviour is as for ${readsocket with a Unix + domain socket. + + Version 4.61 ------------ -PH/01 There is a new global option called disable_ipv6, which does exactly what - its name implies. If set true, even if the Exim binary has IPv6 support, - no IPv6 activities take place. AAAA records are never looked up for host - names given in manual routing data or elsewhere. AAAA records that are - received from the DNS as additional data for MX records are ignored. Any - IPv6 addresses that are listed in local_interfaces, manualroute route - data, etc. are also ignored. If IP literals are enabled, the ipliteral - router declines to handle IPv6 literal addresses. - -PH/02 There are now 20 of each type of ACL variable by default (instead of 10). - It is also possible to change the numbers by setting ACL_CVARS and/or - ACL_MVARS in Local/Makefile. Backward compatibility is maintained if you - upgrade to this release with existing messages containing ACL variable - settings on the queue. However, going in the other direction - (downgrading) will not be compatible; the values of ACL variables will be - lost. - -PH/03 If quota_warn_message contains a From: header, Exim now refrains from - adding the default one. Similarly, if it contains a Reply-To: header, the - errors_reply_to option, if set, is not used. - -PH/04 The variables $auth1, $auth2, $auth3 are now available in authenticators, - containing the same values as $1, $2, $3. The new variables are provided - because the numerical variables can be reset during string expansions - (for example, during a "match" operation) and so may lose the - authentication data. The preferred variables are now the new ones, with - the use of the numerical ones being deprecated, though the support will - not be removed, at least, not for a long time. - -PH/05 The "control=freeze" ACL modifier can now be followed by /no_tell. If - the global option freeze_tell is set, it is ignored for the current - message (that is, nobody is told about the freezing), provided all the - "control=freeze" modifiers that are obeyed in the current message have - the /no_tell option. - -PH/06 In both GnuTLS and OpenSSL, an expansion of tls_privatekey that results - in an empty string is now treated as unset. - -PH/07 There is a new log selector called sender_verify_fail, which is set by - default. If it is unset, the separate log line that gives details of a - sender verification failure is not written. Log lines for the rejection - of SMTP commands (e.g. RCPT) contain just "sender verify failed", so some - detail is lost. - -PH/08 The default for dns_check_names_pattern now allows slashes within names, - as there are now some PTR records that contain slashes. This check is - only to protect against broken name servers that fall over on strange - characters, so the fact that it applies to all lookups doesn't matter. - -PH/09 The default for rfc4131_query_timeout has been changed from 30s to 5s. - -PH/10 When compiled on FreeBSD, NetBSD, or BSD/OS, the pipe transport has a new - Boolean option called use_classresources, defaulting false. If it is set - true, the setclassresources() function is used to set resource limits - when a pipe transport is run to perform a delivery. The limits for the - uid under which the pipe is to run are obtained from the login class - database. - -PH/11 If retry_interval_max is set greater than 24 hours, it is quietly reset - to 24 hours. This avoids potential overflow problems when processing G - and H retry rules, and it seems reasonable to require a retry at least - once a day. - -PH/12 When the plaintext authenticator is running as a client, the server - challenges are now checked to ensure they are valid base64 strings. The - default action on failure is to abort the authentication. However, if - client_ignore_invalid_base64 is set true, invalid responses are ignored. - -PH/13 When the plaintext authenticator is running as a client, the challenges - from the server are placed in $auth1, $auth2, etc. as they are received. - Thus, the challege that is received in response to sending the first - string (with the AUTH command) can be used in the expansion of the second - string, and so on. Currently, up to 3 challenge strings are available in - this way. If an invalid base64 string is received when client_ignore_ - invalid_base64 is set, an empty string is put in the $auth variable. - -PH/14 Messages created by the autoreply transport now contain a References: - header. This is constructed in accordance with rules that are described - in section 3.64 of RFC 2822, which states that replies should contain - such a header line, and section 3.14 of RFC 3834, which states that - automatic responses are not different in this respect. However, because - some mail processing software does not cope well with very long header - lines, no more than 12 message IDs are copied from the References: header - line in the incoming message. If there are more than 12, the first one - and then the final 11 are copied, before adding the message ID of the - incoming message. +The documentation is up-to-date for the 4.61 release. Major new features since +the 4.60 release are: + +. An option called disable_ipv6, to disable the use of IPv6 completely. + +. An increase in the number of ACL variables to 20 of each type. + +. A change to use $auth1, $auth2, and $auth3 in authenticators instead of $1, + $2, $3, (though those are still set) because the numeric variables get used + for other things in complicated expansions. + +. The default for rfc1413_query_timeout has been changed from 30s to 5s. + +. It is possible to use setclassresources() on some BSD OS to control the + resources used in pipe deliveries. + +. A new ACL modifier called add_header, which can be used with any verb. + +. More errors are detectable in retry rules. + +There are a number of other additions too. Version 4.60
