Looks like it might be the IPBlock custom function, which allows you to
throttle the number of messages received from a given sender within an
hour. However, the description says that this pertains to all types of
senders (spam, virus, annoyances, and even mail from Mom). I'll hold out
and see if anyone else can clarify.

Vispan's author (formerly mailstats) used to automatically add
persistent virus senders to the access.db as part of the stats
collection cron job. He told me he didn't include this feature in the
latest build because Julian had included the same functionality in
MailScanner.
