The doc/ChangeLog file contains a listing of all changes, including bug fixes. - -Version 4.51 +Version 4.61 ------------ -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. - - 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. - - 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: - - # 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 - - If Exim never has to generate the parameters itself, the possibility of - stalling is removed. - -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 - - 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.) - - If you enable EXPAND_DLFUNC, you should also be aware of the new redirect - router option forbid_filter_dlfunc. If you have unprivileged users on - your system who are permitted to create filter files, you might want to - set forbid_filter_dlfunc=true in the appropriate router, to stop them - using ${dlfunc to run code within Exim. - - You load and call an external function like this: - - ${dlfunc{/some/file}{function}{arg1}{arg2}...} - - Once loaded, Exim remembers the dynamically loaded object so that it - doesn't reload the same object file in the same Exim process (but of - course Exim does start new processes frequently). - - 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: - - int dlfunction(uschar **yield, int argc, uschar *argv[]) +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. + + +Version 4.60 +------------ - Where "uschar" is a typedef for "unsigned char" in local_scan.h. The - function should return one of the following values: +The documentation is up-to-date for the 4.60 release. Major new features since +the 4.50 release are: - OK Success. The string that is placed in "yield" is put into - the expanded string that is being built. +. Support for SQLite. - FAIL A non-forced expansion failure occurs, with the error - message taken from "yield", if it is set. +. Support for IGNOREQUOTA in LMTP. - FAIL_FORCED A forced expansion failure occurs, with the error message - taken from "yield" if it is set. +. Extensions to the "submission mode" features. - ERROR Same as FAIL, except that a panic log entry is written. +. Support for Client SMTP Authorization (CSA). - 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. +. Support for ratelimiting hosts and users. -TF/01 $received_time is a new expansion variable containing the time and date - as a number of seconds since the start of the Unix epoch when the - current message was received. +. New expansion items to help with the BATV "prvs" scheme. -Version 4.50 ------------- +. 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. ****
