Although I know the answer will be "check your MTA" I thought I'd throw this one out to the list anyway.
RH 7.1 + Postfix (chroot'd) + Mailman 2.0.8 Sending out a newsletter to ~12000 subscribers. One group of addresses, all at the same domain, received multiple copies of the email (~20 each). Every entry in maillog is identical except for the timestamp and shows status=sent (250 Ok). IP's and names replaced to protected the harassed. Feb 24 23:31:03 lists postfix/smtp[13929]: 049AA27294: to=<[EMAIL PROTECTED]>, relay=smtp.replaced.com[1.2.3.4], delay=0, status=sent (250 Ok) Feb 24 23:32:04 lists postfix/smtp[14206]: C9FC2272AC: to=<[EMAIL PROTECTED]>, relay=smtp.replaced.com[1.2.3.4], delay=1, status=sent (250 Ok) Feb 24 23:33:02 lists postfix/smtp[14206]: C1A7B272AC: to=<[EMAIL PROTECTED]>, relay=smtp.replaced.com[1.2.3.4], delay=1, status=sent (250 Ok) Feb 24 23:34:02 lists postfix/smtp[14206]: 8F5C1272AC: to=<[EMAIL PROTECTED]>, relay=smtp.replaced.com[1.2.3.4], delay=0, status=sent (250 Ok) Feb 24 23:35:02 lists postfix/smtp[14206]: 35766272AC: to=<[EMAIL PROTECTED]>, relay=smtp.replaced.com[1.2.3.4], delay=0, status=sent (250 Ok) Feb 24 23:36:03 lists postfix/smtp[14206]: EFED6272AC: to=<[EMAIL PROTECTED]>, relay=smtp.replaced.com[1.2.3.4], delay=1, status=sent (250 Ok) It's doing this retry every minute, per qrunner cron job I suppose. Users are only subscribed once, strings on config.db show the users have three entries each (which everyone appears to have). In Postfix I've altered the queue lifetime and set the minimal retry time to 10 hours to limit repeated sends. To top it all off, after shutting down Postfix and clearing the queues, the repeats started again once Postfix was back up. Shutdown, cleared everything, rebooted the server, back up, same problem. Two addresses at the same domain continue to get hammered. Recursive grep'ing on mailman directory shows only the config.db and config.db.last file have entries for the user's names. Any ideas? What else can I check?
