Dear Sirs,

We have been using Mail Man on our Linux based Mail Server for the last three weeks to mail to our Newsletter list of nearly 50,000 members. Everytime we send the Newsletter our Mail Server goes down. This only happens when we use Mail Man. Are there issues with the number of people that Mail Man can mail to. Mail Man seems to work flawlessly when we send test message to small list groups. It is only when we launch to our total list of 50,000 there is an issue that arises.

This is most likely a problem with insufficient RAM. Try doubling the memory in your server.

We have also noticed that none of our AOL members now get the Newsletter. Have you heard of anything that can be done to help with this issue. We know AOL has changed there SPAM variables recently. We didn't know if something could be set with in Mail Man to get through this issue.

You can use VERP (look in the FAQ...). There are also several discussions of this in the archives of the list.
