Can anyone recommend a good POP3 Webmail server? I see a few, but I'd like to hear some opinions since it's for a enterprise establishment.

I always thought the reason all the webmail solutions I saw were imap is because the webserver is local to the boxes. It seems silly to poll the email server on the same machine or same rack and put the message in 2 places. Why don't you want to use webmail with imap and provide pop3 for external if they have to have it?

Well here's the catch. The mail is external. It gets pulled locally, but only for POP3. I guess I could see what I could do with Horde or something.

The new Horde is nice. I installed it a couple of days ago and it's far easier to configure than the previous version. Very nice, IMHO.
That said, openwebmail (http://openwebmail.org)/neomail (http://neocodesolutions.com/software/neomail/) support pop3 but I have never played with them.
