It'd be much better, because I would allow me to mix overquota and
no-overquota recipients.
But the problem in my case is that I am using some hashing to
distribute the users' mailboxes, dovecot can handle this easily
because it supports some interesting stuff

With a perl script I could also do that, I would like only if it's the
last resort (too much overhead I would think)
