題目: [exim] Exim 4.70: Release Candidate 3
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)


   TK/03 Added patch by Wolfgang Breyha that adds experimental DCC
         (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.

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.


   NM/02 Bugzilla 646: Removed unwanted C/R in Dovecot authenticator

         after a local_part_suffix or local_part_prefix option, Exim now

         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

so
         that they are available at delivery time.


TF/07 Fix the way ${extract is skipped in the untaken branch of a
conditional.

   TF/08 TLS error reporting now respects the incoming_interface and

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.
