New Features in Exim
--------------------
updated when there is a relatively large batch of changes). The doc/ChangeLog
file contains a listing of all changes, including bug fixes.
-
-Version 4.51
+Version 4.60
------------
-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
+The documentation is up-to-date for the 4.60 release. Major new features since
+the 4.50 release are:
- 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:
+. Support for SQLite.
- ${dlfunc{/some/file}{function}{arg1}{arg2}...}
+. Support for IGNOREQUOTA in LMTP.
- 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).
+. Extensions to the "submission mode" features.
- 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:
+. Support for Client SMTP Authorization (CSA).
- int dlfunction(uschar **yield, int argc, uschar *argv[])
+. Support for ratelimiting hosts and users.
- Where "uschar" is a typedef for "unsigned char" in local_scan.h. The
- function should return one of the following values:
+. New expansion items to help with the BATV "prvs" scheme.
- OK Success. The string that is placed in "yield" is put into
- the expanded string that is being built.
-
- FAIL A non-forced expansion failure occurs, with the error
- message taken from "yield", if it is set.
-
- FAIL_FORCED A forced expansion failure occurs, with the error message
- taken from "yield" if it is set.
-
- 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 4.50
-------------
+. 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.
