[Mailman-Users] Automatically reject Spamassassin Tagged Spam?

[Ralf Hildebrandt]

We're using Mailman 2.1.3 together with SpamAssassin. One of my lists
is being swamped with spam that I have to discard manually.

How can I configure Mailman to automatically discard Mails that have "***
SPAM ***" in the subject header?
