This is a really nice server, but for one drawback: it will allow through illegal message-IDs, and so it doesn't work with Outlook XP if you get a lot of spam (which frequently has such message IDs). Contact them and they'll claim it's Outlook's fault, which it is, really, but that's not a really useful position from my point of view. In fact, their support department had a very "The Customer is Always Wrong" attitude the entire time I worked with them.

Too bad, really, because otherwise the server is just the software I'd like it to be: easy to use, full-featured, etc., etc.
