I did the upgrade and I cna log in using the regular web interface and everything is dandy there. The problem is I was using IMAP (SSL) to get my mail and now it does not work. When I use IMAP w/o SSL the password does not work, although on the web interface the password works fine. Also, https: use to work and now it does not respond., it only responds for Zimbra admin on port 7071.
On a side note: I had the M1 installed where I was able to have my web server monitor port 80 and had zimbra monitoring port 443 .... please tell me I can stil do thsi with some sort of hack. I would be eternally grateful to get back to the way it worked before.
BTW . I don't think this is a firewall issue ( it was working before using these ports).
