[Mailman-Users] Does mailman support a MySQL backend?

I'm using RH 7.3 and I have a DSL line @ 256k upload - I havn't even
attempted to send messages to list anymore, because I can't even get the web
interface to come up, it times out. I adjusted the cf files manually to show
3000 addresses per page, and STILL the pages time out. I'm thinking of using
a diffrent application to send out my email. I know a lot of the addresses
are going to bounce, and that is REALLY going to mess up performance, it's
such a shame, we've spent FOUR years collecting these addreses, from 16
diffrenct universities up and down England. The thing that worries me, is
the bouncing mail, I don't mind if my server takes three days to send all
the mail, it's a one way list, I just want to increase performance when it
comes to admin tasks.

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.
