Recommendations for the Right IMAP Server? 223
eugene ts wong asks: "Our company is planning on taking care of its own email, by setting up our own server. I've been given the task of researching what is out there. So far, I've got my heart set on an IMAP server that we can install on Gentoo. Unfortunately, email isn't our forte, and I really have no idea of where to start. I've made some google searches, browsed around on the IMAP site, and also found this email. According to the mutt documentation, Cyrus and Courier are the best choices." What IMAP servers have you used, and which ones would you recommend?
