Both hosts also have a pretty bad blacklisting problem.
We're starting to switch to webfaction, but webfaction doesn't easily allow you to have your own instance of mailman running.
I'm thinking about paying for a dedicated host for our e-mail servers, which would also ideally have its own instance of mailman installed and a large number of lists and outgoing e-mails allowed. This host would not have a blacklisting issue.
However, I haven't been able to find any reputable recommendations for such a host. Many run-of-the-mill shared hosting plans offer mailman through cpanel, but these are exactly the kinds of hosts I've had issues with.
Has anyone worked with a host that does e-mail servers really well?
