Last week, Friday, mailman stopped sending out and receiving email. I started troubleshooting and found that there were firewall rules that had been changed that appeared to be causing the problem. Those changes were reverted and mailman began receiving email. However it was still not sending out email. I had the Sendmail people check all of the servers to confirm that the servers were sending and receiving. Then, from the mailman server, I ran a manual test against the SMTP server. That resulted in an email to my mailbox:
# telnet relay.csc.com 25 Trying 20.137.2.88... Connected to relay.csc.com (20.137.2.88). Escape character is '^]'. 220 amer-mta102.csc.com; ESMTP Tue, 29 Sep 2009 14:36:36 -0400 helo fcg.com 250 amer-mta102.csc.com Hello [20.8.232.105], pleased to meet you mail from: [email protected] 250 2.1.0 [email protected]...

Here is the email that I received from the test. This would lead me to believe that there is something, within mailman, that is awry. I'm not sure how because it was working prior to Friday, but this is where I am right now. I need to troubleshoot that mailman is still configured correctly. Can someone assist me with this?
