I am in the process of evaluating Zimbra and it's mobile capability. I have the trial for the Network edition, but I can't find any documentation regarding Zimbra Mobile. I found the wiki page, but it doesn't say anything about what firewall port, if any I will have to open up in addtion to the https port that I already opened. Does active sync just use HTTP requests or is it going over the IMAP port? And if documentation does exist, can someone point me in that direction?
