The spammer sent a message to KNOWN_USER and specified UNKNOWN_USER as
the sender. The original message intentionally included a Delivered-To
header. Courier checks that header during local delivery - where genuine
mail loops most likely originate.

You need to filter that trick at the SMTP level, doing a case sensitive
comparison between KNOWN_USER@CORRECT_DOMAIN an the value in the
Delivered-To header. (That's what local delivery does.)
