Subject: [exim-announce] Exim 4.73 Release
Exim release 4.73 is now available from the primary ftp site:
* ftp://ftp.exim.org/pub/exim/exim4/exim-4.73.tar.gz
* ftp://ftp.exim.org/pub/exim/exim4/exim-4.73.tar.bz2

This is primarily a security and bug fix release. The changes
involved are:-

       + CVE-2010-4344 exim remote code execution flaw
       + CVE-2010-4345 exim privilege escalation
 2. Improvements to OpenSSL support.
 3. Convert to a more recent Clam/AV API.
 4. Additional improvements to DKIM support
 5. Remove reliance on C99 va_copy()

CVE-2010-4344 was actually resolved by a fix in release 4.70, but
not identified at the time as a security issue. Changes have been
made in release 4.73 to resolve CVE-2010-4345. We recommend that
users should migrate to 4.73 as soon as possible, however some
distributions are instead using older releases with specific
patches for these issues.

Due to packaging build issues no texinfo documentation files have
been produced - however they should be buildable from the
documentation source should you have the correct toolchain
available. The HTML documentation included is now built using the
same toolchain as the website documentation.

The primary ftp server is in Cambridge, England. There is a list of
mirrors in:
* http://www.exim.org/mirmon/ftp_mirrors.html

The master ftp server is now ftp.exim.org.

The distribution files are signed with Nigel Metheringham's GPG key

on the ftp site and on a number of keyservers. The ASCII signature
files are in the same directory as the tarbundles. The SHA1 hashes
for the distribution files are:
