Actually, I read something else in this statement. We still use Sendmail
(yeah yeah, I know :) and occasionally, mostly after receiving a lot of
spam, there is so much mail in the queue that sendmail can't keep up with
incoming mail, let alone catch up on the queue. So we stop sendmail and
start a couple of queueruns, sometimes for some hours. I don't particularly
like the idea of a qrunner starting every minute (or even every ten minutes)
trying to send each and every mail in the queue... it strikes me as fairly
Then again, we currently use the Sendmail delivery module, so I'm not
terribly worried or anything ;-P But perhaps it would be a good idea to
catch some errors (like 'connection refused') and flag them like 'permanent'
errors. But that isn't very straightforward in the current setup, methinks.
