Ok, I've really screwed up here. I was trying to setup a Test server to play with backup/restores, and I ran ZmSetServerName on my test server while my Live server was up. I believe it did something bad. It was working at that moment, but then I issued the commands
zmprov ms mail.domain.com zimbraLmtpAdvertisedName testmail.domain.com
zmprov ms mail.domain.com zimbraServiceHostname testmail.domain.com
immediately, things went bad. I tried to fix it with
zmprov ms testmail.domain.com zimbraLmtpAdvertisedName mail.domain.com
zmprov ms testmail.domain.com zimbraServiceHostname mail.domain.com
and zmSetServerName mail.domain.com, but I can't connect still. webmail won't even load...it just sits there with the loading screen. Please help!
