I'm using EZMLM right now, and while it seems to work well, I need something that makes it easier to chop the lists up into multiple messages before going out. I just read some stuff on Smartlist, and it's little program called choplist which looks like it does what I want. Does Sympa or Mailman do anything like this? Whatever I get is going to have to handle about 20 lists with 150,000 to 400,000 subscribers each. Each list only goes out once per day, so it's not high traffic, just a lot of subscribers. The actual sending of the messages will be done through a heavily modified qmail setup (my smarthost cluster). But the list manager will still have to handle bounces. If I could set it up to where each outgoing message was split up into 16 messages with 1/16 of the subscribers on each one, that would be perfect, as my smarthost cluster has 4 slave servers that get messages distributed to them randomly (so 16 parts would distribute fairly evenly).
