dovecot - Oct 2010 - What causes the quota information to get updated?

Hello,

if new mails arrive, the quota information is updated and reported via
imap immediately. However, after deleting a message, nothing happens.
Even if I delete all messages and the mailbox e.g. was over quota, new 
mails won?t be accepted because the mailbox is over quota.

Is this the way it should be or a misconfiguration?

Couple of guesses:

a) The messages haven't been expunged (only marked with \Deleted flag)

b) The messages still exist in Trash

You could use doveadm to see what messages still exist. For example:

doveadm mailbox status messages '*'
