[MM3-users] Re: Mailman sends Welcome emails, but does not send [List] postings emails

Logs are possibly the most useful. You might find something in mailman.log about the death of whatever runner had died. Looking at queues is also useful. FWIW, looking back at this time period in mailman.log the only instances of "runner exiting" are in groups, at the times when I had manually issued "mailman restart" to try a few different debug logging options. I.e. there was no single / multiple record of "runner exiting" from e.g. an unexpected program fault.
