Upon examining the original message that my MTA bounced, I know this is not
a coincidence.
I trimmed the original message because I thought it was non-relevant, but it
clearly is.
something in the original message confused some part of my MTA; This _is_ a
bug; im just not sure if it's qmail or vpopmail
below is the original email message that my system bounced due to "message
is looping"
Tom!? Ken!? :)

How can this happen?
*Any* header can be forged. :^)
Ok, but I'm not clear on one thing. qmail+vpopmail is going to route
locally based on the to field of the incoming message, right? So you are
saying this message was forged locally, meaning a hacked server?
The envelope recipient ("RCPT TO:") is what qmail mostly cares about.
The normal message headers are fluffy bits of superfluous information
that could help it detect a mail loop.
Your message appears to have had a "To:" header of "[EMAIL PROTECTED]"
(forged) and an envelope recipient of "[EMAIL PROTECTED]" (not forged)
or maybe even some other address that aliases itself to kurt.
Curiously your off-list reply cased my server to generate this message:
message is looping /var/vpopmail/domains/breathsense.com/kkb/Maildir/
Why would your server bounce it in the first place? Fix that!
