We just bought Imail a few weeks ago and discovered it's IMAP server is really slow. After some research, it appeared that everyone has this problem with it. Since we want to support IMAP, this is unacceptable. IMail tech support basically told us to just deal with it.
If you want to just support POP, though, IMail is a good solution.
You may also want to look at Communigate.
