First, your MTA appears to be doing DNS verifies during SMTP from Mailman. This is not good. See <http://www.python.org/cgi-bin/faqw-mm.py?req=show&file=faq04.011.htp>. When your MTA receives the 'rcpt TO:<megan>' and responds with a '451', Mailman queues the message in it's retry queue and retries in 15 minutes. Thus the vast number of attempts to send to 'megan'. The 'megan' address can come from anywhere. It is unlikely to be a list member, but it may be an owner or moderator. Mailman's bin/find-member --owner megan will find an owner or mmember, but not a moderator. More likely, this is a rejection notice in response to a non-member post (undoubtedly spam) to a list. You need to find Mailman's retry queue (normally qfiles/retry, but in FHS compliant RedHat /var/spool/mailman/retry). You can look at the entry/entries with bin/show_qfiles qfiles/retry/* which will show you the contents of the entries. From this, you can then determine the list and whether this is an owner or moderator or just spam and remove the unwanted files from the queue. -- Mark Sapiro <[EMAIL PROTECTED]> The highway is for gamblers, San Francisco Bay Area, California better use your sense - B.
