dovecot - May 2013 - Released Pigeonhole v0.4.0 for Dovecot v2.2.1.

Hello Dovecot users,

I finally release the first version of Pigeonhole v0.4 for Dovecot v2.2. 
The main reason for the delay was that some unexpected (design) problems 
occurred with the new doveadm-sieve plugin, which allows synchronizing 
sieve scripts using doveadm sync.

One important change is that I incorporated the extprograms plugin into 
the main Pigeonhole release. With this plugin it is possible to execute 
administrator-controlled external programs (shell scripts) from the 
Sieve interpreter, e.g. for special message delivery, filtering and 
string manipulation.

The list of new features is not that impressive. I've been working on 
IMAP URLAUTH, IMAP CATENATE and HTTP support for Dovecot. Currently, I'm 
building an SMTP submission proxy server. After all that I plan to spend 
more time on Sieve development. One of the most important issues on my 
list is implementing support for using alternative types of storage 
(e.g. a database) for Sieve scripts, rather than only a filesystem 
directory as it is now.

Changelog v0.4.0:

+ Added doveadm-sieve plugin that provides the possibility to sync
   Sieve scripts using doveadm sync along with the user's mailboxes.
+ Added the Sieve extprograms plugin to the main Pigeonhole package. It
   is still a plugin, but it is now included so that a separate compile
   is no longer necessary and distributors are likely to include it. The
   extprograms plugin provides Sieve language extensions that allows
   executing (administrator-controlled) external programs for message
   delivery, message filtering and string manipulation. Refer to
   doc/plugins/sieve_extprograms.txt for more information.
+ Added debug message showing Pigeonhole version at initialization.
   Makes it very clear that the plugin is properly loaded.
+ Finished implementation of the Sieve include extension. It should now
   fully conform to RFC 6609. The main addition is the new :optional tag
   which  makes the include command ignore missing included scripts
   without an error.
+ Finished implementation of the Sieve environment extension as much as
   possible. Environment items "location", "phase" and
"domain" now also
   return a usable value.

The release is available as follows:

to notify me when there are any problems.

Yay! Thanks so much Stephan.

One question though...
> Currently, I'm building an SMTP submission proxy server.
Can you elaborate on this? Does this mean for example, that we could use 
dovecot as our submission server and auto-save-to-sent, avoiding the 
overhead of the 'Copy to Sent' behavior we are currently forced to use 
where a message is first uploaded when it is sent, then again when it is 
saved to the sent folder?

This would be awesome, as we deal with a lot of large attachments, and 
when people are working from home, it can take many many seconds (even a 
minute or so for very large attachments depending on their internet 
connection speed) to send, and then it has to do it all over again to 
save to sent.

Thanks again!

What about using Dovecot's lib-fs to abstract the storage layer?
