We run Postfix + Cyrus and a some of our users are often "over quota".
Using virtual alias maps in postfix for aliases, leads to the following
effect: the mail is "splitted" by postfix and then requeued for a evety
recipient of the alias (not the alias itself). If submission fails (e.g.
"over quota"), then the mail stays in the queue and submission is
retried regularly.
As the mail was already splitted before the submission attempt to the
mailbox, only the mail for the mailbox that's failing is kept in the

Hope that helps...
