Also...I just found a discussion on the mailman archives of...
Low level smtp error.
I have a different error than this individual had, the error they listed was...
an 16 17:12:32 2007 (9353) Low level smtp error: (111, 'Connection refused'), msgid: <[EMAIL PROTECTED]> Jan 16 17:12:32 2007 (9353) Low level smtp error: please run connect() first, msgid: <[EMAIL PROTECTED]> Jan 16 17:12:32 2007 (9353) delivery to [EMAIL PROTECTED] failed with code -1: please run connect() first Jan 16 17:12:32 2007 (9353) delivery to [EMAIL PROTECTED] failed with code -1: (111, 'Connection refused')
...and folks suggested trying
telnet localhost 25
...from the mailman box. I just tried that command from the mailman box and received the following...which I'm guessing is potentially a source of my problem.
localhost/25: Name or service not known
