Take a look at your maillog and grep the duplicate email address...see if your end actually sent the message to [EMAIL PROTECTED] more than once.

My email didn't get any dups, so I can't check either, and I really DON'T want to replicate it!! I'm going to assume that the problem is my end. If it's mailman screwing up, how can I go about cleaning my list? And if it's my MTA, how do I fix that?? -----Original Message----- From: Nigel Metheringham [mailto:[EMAIL PROTECTED]] Sent: Monday, September 23, 2002 12:52 PM To: Angel Gabriel Cc: Mailman (E-mail) Subject: Diagnosing duplicates [Was:Now MTA tweaking!] Change in subject line - its a different thread...

The answer is you need to get at least 2 of the duplicates (ideally all the duplicates that reached a single address), with the full headers - specifically you need the received lines. You then compare the received headers on each one and work out where the paths of the 2 mails diverged. This could be:- - the original poster sent several copies (happens quite often) in this case you see the received lines are different at every stage - the senders MTA duplicated it (first - thats the bottom one in the message headers - received line is exactly the same, the rest are different). - mailman duplicated it (different received lines on the list delivery MTA) - the list delivery MTA duplicated it (subtly different) - someone's virus scanner reinjected it (they *must* die!!!) - someone's vacation mailer reinjected it (they must die and their whole domain be blocked - actually same applies for the virus scanner too). There are other possibilities too... and never underestimate how determined some idiots can be to loop your mail.
