Do you know whether it's mailman, or your MUA that's the sticky
wicket?

We have one list with 20,000 subscribers.  It used to take several
days to get everybody out.  Inspection revealed it was the MTA,
Postfix, which needed load tuning, and also the Linux kernel,
which needed some kernel parameters bumped up to allow Postfix
the elbow room to run 150 concurrent delivery processes.

Now it takes about three hours for most of the good addresses
on the list to get delivered.  The sticky wicket is the internet
connection, which also supports telecommuters, so we've had
to tune the mailserver to stop short of saturating the connection.
