The doc/ChangeLog file contains a listing of all changes, including bug fixes. +Version 4.63 +------------ -Version 4.51 +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. + + +Version 4.62 ------------ -PH/01 The format in which GnuTLS parameters are written to the gnutls-param - file in the spool directory has been changed. This change has been made - to alleviate problems that some people had with the generation of the - parameters by Exim when /dev/random was exhausted. In this situation, - Exim would hang until /dev/random acquired some more entropy. +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: - The new code exports and imports the DH and RSA parameters in PEM - format. This means that the parameters can be generated externally using - the certtool command that is part of GnuTLS. + ${readsocket{inet:[::1]:1234}{}... - To replace the parameters with new ones, instead of deleting the file - and letting Exim re-create it, you can generate new parameters using - certtool and, when this has been done, replace Exim's cache file by - renaming. The relevant commands are something like this: + 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. - # rm -f new.params - # touch new.params - # chown exim:exim new.params - # chmod 0400 new.params - # certtool --generate-privkey --bits 512 >new.params - # echo "" >>new.params - # certtool --generate-dh-params --bits 1024 >> new.params - # mv new.params params +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. - If Exim never has to generate the parameters itself, the possibility of - stalling is removed. +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. -PH/02 A new expansion item for dynamically loading and calling a locally- - written C function is now provided, if Exim is compiled with - EXPAND_DLFUNC=yes +Version 4.61 +------------ - set in Local/Makefile. The facility is not included by default (a - suitable error is given if you try to use it when it is not there.) - You load and call the function like this: +The documentation is up-to-date for the 4.61 release. Major new features since +the 4.60 release are: - ${dlfunc{/some/file}{function}{arg1}{arg2}...} +. An option called disable_ipv6, to disable the use of IPv6 completely. - Once loaded, Exim remembers it so that it doesn't reload it in the same - Exim process (but of course Exim does start new processes frequently). +. An increase in the number of ACL variables to 20 of each type. - There may be from zero to eight arguments to the function. When compiling - a local function that is to be called in this way, local_scan.h should be - included. The Exim variables and functions that are defined by that API - are also available for dynamically loaded functions. The function itself - must have the following 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. - int dlfunction(uschar **yield, int argc, uschar *argv[]) +. The default for rfc1413_query_timeout has been changed from 30s to 5s. - Where "uschar" is a typedef for "unsigned char" in local_scan.h. The - function should return one of the following values: +. It is possible to use setclassresources() on some BSD OS to control the + resources used in pipe deliveries. - OK Success. The string that is placed in "yield" is put into - the expanded string that is being built. +. A new ACL modifier called add_header, which can be used with any verb. - FAIL A non-forced expansion failure occurs, with the error - message taken from "yield", if it is set. +. More errors are detectable in retry rules. - FAIL_FORCED A forced expansion failure occurs, with the error message - taken from "yield" if it is set. +There are a number of other additions too. - ERROR Same as FAIL, except that a panic log entry is written. - When compiling a function that is to be used in this way with gcc, - you need to add -shared to the gcc command. Also, in the Exim build-time - configuration, you must add -export-dynamic to EXTRALIBS. +Version 4.60 +------------ +The documentation is up-to-date for the 4.60 release. Major new features since +the 4.50 release are: -Version 4.50 ------------- +. Support for SQLite. + +. Support for IGNOREQUOTA in LMTP. + +. Extensions to the "submission mode" features. + +. Support for Client SMTP Authorization (CSA). + +. Support for ratelimiting hosts and users. + +. New expansion items to help with the BATV "prvs" scheme. + +. A "match_ip" condition, that matches an IP address against a list. -The documentation is up-to-date for the 4.50 release. +There are many more minor changes. ****
