[Spambayes] filtering in the face of disk quotas or full disks

[Skip Montanaro]

Has anybody thought about how any of the Spambayes tools would perform in
the face of disk quotas or full disk partitions?  Here at Northwestern they
are going to start supporting IMAP (against their better wishes, but the
customer is always right).  Because they have roughly 30,000 active email
accounts and IMAP allows (requires?) mail to be stored on the server, they
are going to institute disk quotas on the mail servers for the first time.
Procmail+SpamAssassin seems to be breaking in some situations and SA is
(incorrectly, I believe) getting egg on its face as a result.  I'd like to
make sure Spambayes has these various problems addressed.
