Each .pck is a separate email message (to one recipient)?  Or each one 
is a separate post with many recipients?  Is 80-100 items in queue/out 
a lot?

I have another MLM that typically hands messages off to this MTA at 
20-30/second, and I wrote it, so I know it isn't fast.  :)

  Does Mailman send messages out serially?

Is there any way for me to examine these files?  Or do I need to be a 
Python programmer for that?

Aha!  There is one very big file in there.  I shall whack it.
