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!?

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?
