Hmm. Well, I said it because I have a quarantine rule in place that
places non-authenticated-external-source-local-sender messages in a
suspect folder for manual review. It catches *very* few messages
(less than 1 per week).

However, to get filtered this way messages first have to make it past
the DNSBL, spoofed HELO, sender verify, etc checks. And as I
mentioned mine is a low volume server (small business with a few
hundred legitimate and a few thousand bogus messages/day). That's
probably why our observations are different.
