The main thing here is to look at the TO: and FROM: fields entry and strip
them away from any Cc: and Bcc: that the possible spammer may add to those
fields to be able to send the message to other places than you want them to.

You can look at the "Hacked by Spammer" thread (first post 10th of Jan 2006,
poster Dan) for how to do the filtering.
