I've been trying to get push email via IMAP Idle on my Windows device for some time now. I ran across something called Z-Push yesterday that makes the mail server look like an Exchange server to utilize Activesync for push email. Looking at the install scripts, it does require such modifications as writing to /var/www from the webroot, as well as editing the httpd.conf file (Both of which I we lack permission to do). Has anyone ever got this solution to work, or know of a way to do the proper editing of these directories/files to install this. This looks like a very interesting solution for push email.
