[Mailman-Users] Strange bounce removal issue

[Brian Carpenter]

Hey Mailman Users,

I have a strange issue affecting a client's mailing list. It seems the
mailman server is repeatedly removing an e-mail address due to excessive
bounces. I see this in the subscribe log file:

Mar 22 20:38:04 2009 (26386) listname_list.domain.com: deleted
email at verizon.net; disabled address
Mar 22 20:38:04 2009 (26386) listname_list.domain.com: email at verizon.net
auto-unsubscribed [reason: BYBOUNCE]

These entries actually go on for about 3 days, and seem to occur in the late
evening/ early morning hours. Since the administrator of the list is
notified when a member is removed due to bounces, he keeps receiving
repeated notices regarding the same e-mail address.

This issue does effect different e-mail address but the same list and it is
very random. I have not received any reports from my other clients, just
this particular one.

I really could use some assistance in troubleshooting this. Thanks!

Regards,
Brian
