Mail Server

[fonnerk]

What is a good mail server for linux.

I was looking for these features...
IMAP (with the ability to nest folders)
Web Interface
Server side mail (rules) sorting for the individual users
and the ability for it to grab mail for a domain out of a single pop mailbox and sort it into each of the accounts on the mailserver.

Thanks,
