I've included some of the diagnostics that was requested. As of this moment there are 7423 messages in the qfiles directory for mailman. And it continues to grow. Please let me know if my thinking is flawed on how mails flow through the system.
1. Message to a list hits sendmail initially and goes into the mqueue directory for sendmail for processing. 2. Sendmail delivers the message to the mailman wrapper which places the message in the qfiles directory for qrunner to process. 3. qrunner picks up these messages one by one, and delivers the message to each of the recpts listed for the list. How does qrunner decide which email to process? Is there a way to have it process a certain message in the qfiles directory? Are there any utilities for determining what is in the queue or why it was queued by qrunner. I really do appreciate all the help. Yes.. I am using sendmail as my MTA. Trying 127.0.0.1...
