GNU Anubis

This release does an automatic correction of MAIL
and RCPT SMTP commands, fixes loop-detection code,
introduces new configuration keywords (sasl-realm,
sasl-hostname, and sasl-service), and adds new
Danish, Indonesian, Italian, and Swedish message
translations.

The package is now licensed under GPL version 3. A new MDA working mode has been added. The != ("not match") operator and concatenation operator were implemented. With Guile support enabled, Guile version 1.8.0 or later is required. Handling of regular expressions was fixed, and arbitrary-sized buffers were removed. All memory is now allocated on request. The main configuration file is now processed if the client is recognized or not. Errors in Guile scripts are now caught and displayed early. In previous versions they could cause the subprocess to be aborted. A minor bug in the handling of identd responses was fixed.

In this release, the new authentication and
authorization mode has been introduced, which does
not require client machines to run an AUTH server
(identd). It uses the standard SMTP AUTH
capability. The user's database can be kept on the
server machine in any of the following formats:
plain text, GDBM, MySQL, or PostgreSQL. The
program is now extensible via Guile. The
configuration file grammar has been heavily
improved. It features several new syntactical
entities, allows nesting of conditional statements
to arbitrary depth, and is easily extended using
Guile. A test suite was added.

In this release a new format of plain text databases allows
for inclusion of empty fields. Test cases for the AUTH mode
(a.k.a. Dixie) were added. The GPGME support has been
rewritten to work with GPGME 0.9.0 and newer. The XELO
extension has been implemented to speed up the interaction
between the Anubis daemon and anubisusr utility. Checking
user configuration files on remote machine is much faster
due to the use of MD5 sums instead of transferring the entire
file contents for comparison.
