How about

ps auxww| grep qrunner |grep -v grep

It appears that some process or person is stopping Mailman.

How about /var/log/mailman/qrunner ?

And yet you are not logging any smtp debugging in Mailman's error log.
There should be copious log information for every outgoing message.

The above line should cause significant problems when attempting to
create or remove lists. it MUST be one of

MTA = 'Postfix'
MTA = 'Manual'
MTA = None

'Postfix' means generate aliases and virtual-mailman files for Postfix.
'Manual' means display the necessary aliases
None means don't do anything with aliases when lists are created/removed.

What's in the qrunner log?
