According to your list header, you don't have Send= Editor,Hold,Confirm
. Not having that little ",Confirm" on the end--as documented--can leave
you wide open to loops or spoofs. We have been recommending for some
time that announce-only lists be set to Send= Editor,Hold,Confirm . This
forces mail sent even from an Editor to have to be confirmed by that
editor before it can be distributed. It's a little annoying but in the
end it can save you having this problem.
It looks to me like this message actually looped back from a user at
HEALTHGATE.COM . Since it had a From: line with your address, it went
right through. If you'd had ",Confirm" set on the Send= keyword it would
have come to you for approval first.
FYI this is a really common occurance with remote hosts that use the
Microsoft SMTPSVC MTA, which probably isn't 100% RFC compliant. I
suspect the Microsoft product rewrites the RCPT TO: lines in the
envelope, but it's hard to say since we don't use it.
