This is probably a quick one, but I thought I would mail it out to the list. I did check the archives, but didn't have much luck. We are running 2.0.13 and I took on the task of upgrading to 2.1. Our RH-based server is running Sendmail (8.12.7) and happily chugging along managing a few dozen lists for a variety of domains. After upgrading on our test machine (same exact configuration as the production box), changing the smrsh lins to point to the renamed wrapper "mailman", disabling the old qrunner, and starting up the queue runner daemon, it appears that emails TO the list work just fine. However, email FROM the list out to the recipients doesn't happen. For example, I mail into the list as a non-subscribed user. I go to the web interface, and select "approve". The very next entry in the sendmail logs is: Jan 2 11:44:15 testserv sm-mta[29018]: h02GiFBO029018: localhost [127.0.0.1] did not issue MAIL/EXPN/VRFY/ETRN during connection to MTA And then nothing.. no email, nothing. So, I try it as a subscribed user, and I immediately get a message in the sendmail logs as above. I combed through the instructions to no avail. Any ideas would be much appreciated! Thanks! -Rich
