Yes, it is not exactly a straightforward solution. I would like a more
modular mail system which would give us more hooks to handle incoming
mail. I know you can create milters, etc, but those are not a trivial
thing to build. I once created extensions to the Apache web server
with mod_perl which was really quite easy and I was able to make
Apache do something the available extensions could not do alone.  (SSL
secured reverse proxy with LDAP lookup)

There is the James mail server which was created with Java which I
believe had plans for plugins.  But I cannot really run Java on my
FreeBSD 5.x server.

Is there a modular IMAP server which has hooks for languages like
Perl, Python or Ruby?
