Thanks.
First you need to make sure you have the Dovecot quote plugins installed
and configured. <http://wiki.dovecot.org/Quota>
Then, you need to use "-e" and temp_errors when delivering, as in the last
example at <http://wiki.dovecot.org/LDA/Exim>. "-e" will return an error
when delivering to an over quota mailbox. temp_errors will tell Exim when
the error should be regarded as temporary.
When this is done, Exim will be unable to deliver messages to over-quota
mailboxes. It will retry in accordance with your retry rules, and send
notifications to the sender. It won't email the recipient, since the
recipient can't receive emails.
There's a dovecot plug-in to enable IMAP notifications when over quota. If
your users aren't using IMAP, then you will need to arrange that they are
emailed when their mailbox gets to, say 90% of quota. For that, I think,
you'll need a cron job to find the mailbox sizes. I don't know how you'd do
that, because I don't know how dovecot stores its email. In the worst case,
you'd need to use an IMAP query.
