OMG! Yes! That was an amazing bit of diagnositic analysis. :-) A snippet of some anti-spam that has been there for so long I had completely forgotten all about it. Frankly I can't even remember exactly why I have it there now. # Try to defeat spammers using injected Delivered-To headers. /^(Delivered-To:.*@proulx\.com)$/ REPLACE X-$1 /^(X-Delivered-To:.*@proulx\.com)$/ REPLACE X-$1 /^(X-X-Delivered-To:.*@proulx\.com)$/ REJECT mail forwarding loop detected I removed those and of course that fixes the problem. I can't believe it was a self-inflicted problem and I hadn't realized it. THANK YOU! Bob
