I'm using Postfix + Dovecot on a server at the moment - seems to work
very well. I've run Courier before but I much prefer dovecot's more
Dovecot "feels" like the postfix of the IMAP world - I'm not sure how to
explain that but check out www.dovecot.org and you might see what I mean!
How are other people's experiences with Dovecot? It's supposed to be in
the early days of development but it seems really stable to me.
