I apologize if this has been covered but to date, I've not found anything.
I'm running Zimbra 5.0 Open-Source and everything installed and is working correctly except for IMAP.
When I attempt to connect I get a message that the login failed. This very same login works on the web client so I know it's an issue with IMAP to either ports 143 or 993. When I use the non-proxy ports specified in the configuration for IMAP, everything begins to work.
The logs also do not show any errors when I try to connect and fail.
Any guidance on what I need to be doing would be appreciated.
