Hello Dovecot users,
Finally, after little more than a year, I finished the first release of
the new Sieve implementation for Dovecot.
The main reason for rewriting the Sieve engine is to provide more
reliable script execution and to provide better error messages to users
and system administrators. Also, since the Sieve language evolves
quickly, with new language extensions published every year, the aim is
to provide support for quickly extending the engine with new features.
This implementation aims to comply to RFC8225 and it provides support
for the following Sieve language extensions:
In comparison to the old CMU Sieve plugin, I added support for the very
useful variables extension. However, the notify extension is notably
missing. This will be implemented for next major release (0.2.x).
Refer to the README file for a full list of its features:
The source package is available as follows:
Alternatively, it can be cloned from the mercurial repository:
hg clone http://hg.rename-it.nl/dovecot-libsieve
The compilation procedure is identical to the cmusieve plugin
(http://wiki.dovecot.org/LDA/Sieve). Don't forget to execute
./autogen.sh first if you obtained the sources through mercurial. This
release will not compile against Dovecot versions older than v1.2.alpha3.
The configuration is very similar to the original plugin as well. The
most notable difference is the name of the plugin, which is simply
'sieve' in stead of 'cmusieve'.
After compilation, the Sieve engine can be verified before deployment
using the included test suite. This is done by executing `make test` in
the top of the source tree. The test suite is known to finish flawlessly
on the i386 and amd64 platforms. The test suite is not very
comprehensive yet, as it only tests the evaluation of scripts and omits
testing the actual execution of actions.
As this release contains about 30k effective lines of fresh code, bugs
will eventually surface. Make sure that you provide enough information
to reproduce the problem if you report bugs, i.e. the script and the
mail message that caused the problem and/or relevant log entries.
Have fun testing the new Sieve plugin. Don't hesitate to notify me when
there are problems.
