*My* inbox gets filled with thousands of emails, more or less commercial content and trivial notifications from shopping online, and postfix crashes and will not accept new messages if the file "/var/mail/justina" becomes too large.

Configuring postfix to deliver the mail to "~/Maildir" solved that problem.

I still need to configure a sieve or a filter or some nicer mechanism to clear out messages that are either outright spam or too old or no longer of interest to me.

We need to move all users from one (pretty old) installation of dovecot

The old one uses mdbox for users' mailboxes and maildir for
shared/public mailboxes.
The new one must be maildir only.

why did you decide to move to maildir?
