Hi Boni, all,

 I have been using only postfix and exim; but in postfix you can add your
own mail delivery daemons, maybe it would be better to add a new
one - still based on mail.local - to qmail.

 JWebmail has a good plugin support, I think you can do it with relative
easily if you have a good understanding in Java. Also, we - developers -
can help you. Unfortunately we do not have too much time for JWebmail
at the moment, but it can change.

 As a developer, we use it as well ofcourse. The scenario is twenty virtual
hosts with seventy users on an Intel Celern 800Mhz UP, 256Mb RAM,
IBM SCSI disks (10k RPM). J2SDK 1.4.1_02, Tomcat 4.1.18, JWebmail
CVS works well. This machine has everything on it (postfix, courier-imap
and mysql as the user database), as well as other - not commonly used -
services. Forgot one thing, this machine is owned by the Linux Support
Center (Hungary).

Sincerely,
GCS
