The doc/ChangeLog file contains a listing of all changes, including bug fixes. +Version 4.63 +------------ + +1. There is a new Boolean option called filter_prepend_home for the redirect + router. It defaults true, for backward compatibility. If a "save" command in + an Exim filter has a relative path for its argument, and $home is defined, + it is automatically prepended to the relative path. This action can now be + prevented by setting filter_prepend_home false. + +2. There is a new acl, set by acl_not_smtp_start, which is run right at the + start of receiving a non-SMTP message, before any of the message has been + read. (This is the analogue of the acl_smtp_predata ACL for SMTP input.) The + result of this ACL is ignored; it cannot be used to reject a message. If + you really need to, you could set a value in an ACL variable here and reject + based on that in the acl_not_smtp ACL. However, this ACL can be used to set + controls, and in particular, it can be used to set control=suppress_local_ + fixups, which cannot be used in the acl_not_smtp ACL because by the time + that ACL is run, it is too late. When the acl_not_smtp_start ACL is run, the + sender and recipients are known, so the "senders" and "sender_domains" + conditions and $sender_address and $recipients variables can be used. + Variables such as $authenticated_ sender are also available. It is possible + to specify added header lines in this ACL. + +3. When an SMTP error message is specified in a "message" modifier in an ACL, + or in a :fail: or :defer: message in a redirect router, Exim now checks the + start of the message for an SMTP error code. This consists of three digits + followed by a space, optionally followed by an extended code of the form + n.n.n, also followed by a space. If this is the case and the very first + digit is the same as the default error code, the code from the message is + used instead. If the very first digit is incorrect, a panic error is logged, + and the default code is used. This is an incompatible change, but it is not + expected to affect many (if any) configurations. It is possible to suppress + the use of the supplied code in a redirect router by setting the + smtp_error_code option false. In this case, any SMTP code is quietly + ignored. + +4. There is a new parameter for LDAP lookups called "referrals", which takes + one of the settings "follow" (the default) or "nofollow". The latter stops + the LDAP library from trying to follow referrals issued by the LDAP server. + +5. Version 20070721.2 of exipick now included, offering these new options: + --reverse + After all other sorting options have bee processed, reverse order + before displaying messages (-R is synonym). + --random + Randomize order of matching messages before displaying. + --size + Instead of displaying the matching messages, display the sum + of their sizes. + --sort [,...] + Before displaying matching messages, sort the messages according to + each messages value for each variable. + --not + Negate the value for every test (returns inverse output from the + same criteria without --not). + + +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. + +2. If a redirect router sets up file or pipe deliveries for more than one + incoming address, and the relevant transport has batch_max set greater than + one, a batch delivery now occurs. + +3. The appendfile transport has a new option called maildirfolder_create_regex. + Its value is a regular expression. For a maildir delivery, this is matched + against the maildir directory; if it matches, Exim ensures that a + maildirfolder file is created alongside the new, cur, and tmp directories. + + 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. +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
