Browsing around looking for a possible solution to having many different ActiveSync capable phones and an IMAP server. Wanted to get a better handle on the push email that some providers offer, but not from a Dovecot IMAP server.

Came across; http://z-push.sourceforge.net/soswp/ [Z-Push]. It emulates the requests and responses of an ActiveSync server but pulls mail from IMAP and other providers on the local machine.
