Moving mail to Chek

We really need to get our php.net mail forwarding off of circle.net. I would like to move things either to the www.php.net box, or possibly to the new VA box which is supposed to be on the way. Beyond forwarding, I'd like to actually move my mailbox to this new place. I think Andi is currently doing this through POP, and I am a die-hard IMAP user, so it would be nice if we had a decent POP/IMAP setup. The other possibility is to use Mark's setup on chek.com, but it sounds like a hassle for him to give us direct pop/imap access and we are perfectly capable of setting this up ourselves. I built a huge pop/imap mail service a couple of years ago but haven't played with it since. If anybody has built something recently and have some software suggestions, I'd like to hear them. -Rasmus
