I've had a lot of requests recently for information about Mailman hosting. As a general rule I don't like to recommend any particular hosting company. But if you do provide Mailman hosting facilities, please make sure you've added yourself to the PythonHosting wiki:

I usually point people here for more information, so please make sure you're on that list. Now to check the FAQ and see if it points here...
