A clarification: it doesn't actually look at the email headers, but the
envelope (the smtp RCPT TO: <> lines).  If you receive a mailinglist or
BCC'd email, your address may not be in the headers at all.

Milters get the raw text from the "RCPT TO" command.  If you add the -x
switch to spamass-milter, it will run that address through sendmail
again to expand it out to the final delivery address, which will help
if you have lots of aliases or virusertable rewriting going on.
