Mailman has been running well for months. All of a sudden no traffic is not going out. /var/log/maillog shows no errors. Mailman's smtp-failure shows:

This seems to have just started happening this morning. Upstream mail agent is an exchange system front end. Exchange is running fine, etc. Exchange guy is looking at logs... Any ideas anyone ? ------------------------------------------------------ Mailman-Users mailing list Mailman-Users@python.org http://mail.python.org/mailman/listinfo/mailman-users Mailman FAQ: http://wiki.list.org/x/AgA3 Security Policy: http://wiki.list.org/x/QIA9 Searchable Archives: http://www.mail-archive.com/mailman-users%40python.org/ Unsubscribe: http://mail.python.org/mailman/options/mailman-users/archive%40jab.org
