[Dovecot] Quota Messages

[Hermann wacker]

Hi @all,

First: I'm sorry when my english isn't understandable, please just ask
if I messed things up.

I switched from Cyrus to Dovecot (Cyrus was on Debian Sarge, Dovecot
is now on a Etch) and I'm quite happy with it. There is just one thing
that I'm missing in Dovecot. in Cyrus when users reached 90% of their
Quota, a message popped up in their Mailclients, telling them to clean
up their Mailboxes. Dovecot delivers the quotausage to the Client (I
can see in my Thunderbird a small Statusbar), but when you don't look
carefully, you will mostly miss the point where you can delete the
messages without having a fight with the quotalimit (because mails in
trash using the quota).
At the moment I'm using "quota = fs" so there is no good way to keep
the trash out of the quotathing and that's not the point of my
question.
The question is: Is there a way where Dovecot (or Postfix) inform the
user that his quota is reaching its limit? Or maybe the postmaster,
thats not important. The important thing is a way where my mailsystem
tells somebody that quotas are reaching their limits.
