Announcing the 3rd Release Candidate for the exim 4.70 release - we
intend this to be the final release candidate unless any release
blocking bugs are discovered.
The release of Exim 4.70 is on the horizon. A lot of stuff has
accumulated in CVS since January 2008. Since we want to give the current
code some wider exposure, please accept this invitation to test a 4.70
pre-release. You can get the current code by pulling a snapshot from
David's GIT shadow:
git clone git://git.exim.org/exim-src.git
or from the CVS - see
http://wiki.exim.org/EximDevelopment
In either case the RC3 is tagged with exim-4.70_RC3
Or wget a tarball here:
ftp://ftp.exim.org/pub/exim/exim4/exim-4.70_RC3.tar.gz
with (PDF format only) spec documentation at
ftp://ftp.exim.org/pub/exim/exim4/exim-pdf-4.70_RC3.pdf
These files will be mirrored out to the exim ftp mirrors - see
http://www.exim.org/mirmon/ftp_mirrors.html
Feel free to post testing results to the exim-dev list - no matter if
positive or negative.
The main new features are:
* Native DKIM support without an external library.
Docs: http://www.exim.org/~tom/doctest/ch54.html
* Experimental DCC support via dccifd (contributed
by Wolfgang Breyha). See further below for docs.
Other changes:
* PCRE removed from Exim distribution. You will need
a separate PCRE library (and matching headers) to
compile Exim.
* Experimental Yahoo! Domainkeys support dropped in
favor of native DKIM support.
Here's the full changelog:
TK/01 Added patch by Johannes Berg that expands the main option
"spamd_servers" if it starts with a dollar sign.
TK/02 Write list of recipients to X-Envelope-Sender header when
building
the mbox-format spool file for content scanning (suggested by
Jakob
Hirsch)

(http://www.dcc-servers.net/) support via dccifd. Activated by
setting EXPERIMENTAL_DCC=yes in Local/Makefile. Check out
experimental_spec.txt for more documentation.
TK/04 Bugzilla 673: Add f-protd malware scanner support. Patch
submitted
by Mark Daniel Reidel <mr@???>.
NM/01 Bugzilla 657: Embedded PCRE removed from the exim source tree.
When building exim an external PCRE library is now needed -
PCRE is a system library on the majority of modern systems.
See entry on PCRE_LIBS in EDITME file.

conversation. Added nologin parameter to request.

TF/03 Bugzilla 615: When checking the local_parts router precondition
after a local_part_suffix or local_part_prefix option, Exim now
does not use the address's named list lookup cache, since this
contains cached lookups for the whole local part.
NM/05 Bugzilla 521: Integrated SPF Best Guess support contributed by
Robert Millan. Documentation is in experimental-spec.txt
TF/04 Bugzilla 668: Fix parallel build (make -j).

Documentation for experimental dccifd support
---------------------------------------------
*) Building exim
In order to build exim with DCC support add
EXPERIMENTAL_DCC=yes
to your Makefile. (Re-)build/install exim. exim -d should show
EXPERIMENTAL_DCC under "Support for".
*) Configuration
In the main section of exim.conf add at least
dccifd_address = /usr/local/dcc/var/dccifd
or
dccifd_address = <ip> <port>
In the DATA ACL you can use the new condition
dcc = *
After that "dcc_header" contains the X-DCC-Header.
*** WARNING: return codes changed from previous releases!
Return values are:
"fail" for overall "R", "G" from dccifd
"defer" for overall "T" from dccifd
"accept" for overall "A", "S" from dccifd
dcc = */defer_ok works as for spamd.
dcc_result contains the overall result from DCC answer
usually you'll use
defer !dcc = *
to greylist with DCC. If
dcc_direct_add_header = true
is set, then the dcc header will be added "in deep" and if the spool
file was already written it gets removed. This forces exim to write
it
again if needed.
This helps to get the DCC Header through to eg. SpamAssassin.
If you want to pass even more headers in the middle of the DATA stage
you can use $acl_m_dcc_add_header to add information from eg. ClamAV.
Be careful. Header syntax is not checked and added "as is".
Have fun!
Nigel.
