We wrote a perl script which notifies users nightly when they're over their
soft quota. This helps the users who did not go over a huge amount and can
be notified. And because the grace period is 7 days, they get 5-6 messages
before account is blocked. Of course it doesn't help the people who
suddenly get a huge attachment and go over their hard quota.
I would love to hear from anyone who was able to tweak procmail or dmail to
give a nice message when the message being delivered will put the person
over soft quota.

I'm thinking about enabling disk quota on our student mail server. I
have done some reading about the support in uw, and I would be happy
using unix quotas. However, before i reinvent the wheel, I wonder if
someone has a working setup to share?
The server is running in blackbox mode, using sendmail and tmail.
The ideal solution would be to give both smtp and imap users a clear
error message, stating that the user is over quota. Is this possible,
and if not, how close can I get? Some generic error message?
Does a switch to procmail+dmail give me better support for quotas at the
MTA/MDA end?
Would this kind of setup have any support for the soft quota limit?
Finally, to prevent a "religious" discussion: I know that mail quotas
are a pain, that disk is cheap, and that our ongoing migration to mix
will solve the backup problem. But when we see emails in the hundreds of
megs (data samples, high resolution images, ...), resulting in gigabyte
mailboxes, we have to have some sort of control.
The other solution I'm considering is a watchdog, which would send some
sort of nagging email to students with too large mailboxes. Maybe an
email each day would teach them to put the files in their public_html
directory and email the url?
