	It's going to depend a lot on your MTA and how it's configured, 
and whether or not you are making use of personalization features.

	Even if you're not using personalization (so that Mailman creates 
the smallest number of messages possible and then hands those off to 
the MTA), the MTA may well deliver messages to the recipients in 
parallel.  So, some users further down the list might receive the 
message before others higher, simply because of the difference in how 
fast/overloaded the recipient mail servers are, etc....

	Without knowing extensive details of your configuration, it's 
going to be impossible to debug this process.  Indeed, even on a mail 
server where I have full access to all available information, I can't 
always tell you what went wrong or what you should do to ensure that 
doesn't happen again.

	And that's for customers who are paying me large sums of money 
for my consulting services.
