My problem is that my system is in a hard-to-access co-lo, which means I 
don't want to risk a reboot that causes problems that can only be 
addressed from a console. So I'm hoping I can avoid the reboot. Otherwise 
I'll have to schedule it for when the box is accessible.....

Don't think so.

Interestingly enough, when I shutdown mailman it reports an SMTP failure 
for a message it appears to have been 'attempting' to send, then 
shuts down. If I have a 'bad' message in the queue, how would I check 
this, and erase/drop it?

Took a run through. Most of the suggestions relate to 'it never worked' 
conditions, as opposed to 'it was working and stopped', or 'it only works 
when I restart it'.
