This setting has no effect whatsoever on this issue. This setting will cause an incoming post to be held if the number of explicit To: and Cc: recipient addresses equals or exceeds that number. It has nothing to do with how a post is delivered. >We are getting the following error in the log file >/var/lib/mailman/logs/smtp-failure (only when list size crosses 80 >email-ids) > >Jan 13 11:47:18 2011 (27459) delivery to manthra...@gmail.com failed with >code -1: Server not connected >................................ >............................. >Same error for all the email-ids in the list Something is causing Postfix to disconnect when the recipient list for the mail exceeds 80 addresses. My best guess is that 25% of your list addresses are invalid and Postfix is doing recipient address verification and disconnecting with a 421 error after 20 invalid addresses. There is a bug in the Python SMTP library <http://bugs.python.org/issue5713> that can cause the above error when this occurs. Regardless of whether or not the above conjecture is correct, try setting SMTP_MAX_RCPTS = 20 in mm_cfg.py and restarting Mailman. This will cause Mailman to deliver list mail to Postfix in separate transactions with no more than 20 recipients each and should solve the problem. -- Mark Sapiro <m...@msapiro.net> The highway is for gamblers, San Francisco Bay Area, California better use your sense - B.
