The only way to do this in Mailman is by breaking the list into sub-lists on different servers. Where is the time spent. I.e. What is the time in the "smtp to LIST for 50000 recips, completed in tttt.ttt seconds" message in Mailman's smtp log. If this is relatively short, the time is mostly being spent in postfix after receiving the message from Mailman. If it's not short, I.e. even 12 hours, you are only delivering 1 recipient per second from Mailman to Postfix. That is really poor. Do you have a caching DNS on the Mailman/Postfix machine?
