Just checked SpamAssassin's files: in all the tests for forged headers
from various mailers, there was no mention of mPOP. Don't know if
other anti-spam tools include these sorts of checks. Maybe the
spammers are trying to circumvent these checks by forging headers from
a relatively new or unknown mailer? Just a thought.
