You've not specified the problem very clearly. How frequently do you expect 
to send messages to this list? Do you have several lists? How urgent are 
the messages? Do they need to be delivered in the space of a few minutes, 
hours, or days?

If you don't need personalised messages, then you can do the VERP in your 
MTA. That should make it much more feasible. Configure Mailman with several 
parallel queue runners to prevent messages to large lists from holding up 
messages to small lists.
