Re: [cobalt-developers] Maibox fill up leading to anti-spamlisting

[Herb Rubin <herbr@xxxxxxxxxxxx>]

All,

I figured out that procmail was telling sendmail (during local deliver)
about being
over quota. Then sendmail was performing the bounce back to the sender. The
trick is to cause procmail to quietly send the new mail message to /dev/null
when
the regular mailbox is full.

I wrote a perl script called quotacheck that I use with procmail that
returns 3 different return codes:

0 = under quota
1 = over quota already
2 = will go over quota with this new mail message

since procmail uses the return codes it was easy to get it to throw away
the incoming mail message. The only drawback is that the procmail script
needs to be installed in everyone's home directory because its a "per user"
not "systemwide" kind of thing.

Now to write a cronjob script that "installs" it on all my mailboxes on the
Raq 4
once a day.  I might post the set of programs once its all working and
documented.
