I've been running Zimbra for several years without a hitch. Recently I performed an upgrade to 8.0.3 on RHEL 6.2 and I'm having no luck accessing the web interfaces (client or admin) or sending receiving mail via any other source (IMAP, POP, etc.). I've checked all the usual logs and nothing jumps out at me. I've tried stopping and starting all service, fixing permissions, and rebooting the system. I even tried taking the "/opt/zimbra" directory and copying to another system and trying the upgrade again. No luck!

Also, DNS and the host file seems in order (I haven't changed anything there in a over a year).

Here's a few bits on info that may help narrow down some things:
