In that case, it seems likely that your delay is in the Mailman queue
management process, and not within sendmail. In that case, I
recently did a slight cleanup on some good stuff that Nigel
Metheringham put into the FAQ Wizard for FAQ 6.6, and I'd recommend
you take a look at it.
<JLS> Brad, good suggestion on FAQ 6.6
This change below seems to have made a great improvement in performance/speed. The smaller batches starting hitting the sendmail queue almost instantly and the forum activities haven't suffered.
Make sure your batch size is small:
SMTP_MAX_RCPTS = 10
Set your qrunner proc to live longer, and extend the lock life:
QRUNNER_LOCK_LIFETIME = hours(10)
QRUNNER_PROCESS_LIFETIME = minutes(15)
QRUNNER_MAX_MESSAGES = 300
Set these to 20 hours, 2 hours and 50000
Thanks for the tip!
