I am have been searching the forums to my issue. It seems the "zmmailboxd is not running" is a common error, however, I have yet to find someone with the same error I am getting. Here is the error I get in /opt/zimbra/log/zmmailboxd.out:
Zimbra server reserving server socket port=110 bindaddr=null ssl=false
Zimbra server reserving server socket port=995 bindaddr=null ssl=true
Fatal error: exception while binding to ports
java.net.SocketException: Unbound server sockets not implemented
I am really hoping someone can help with this because I know my server is accepting mail, however, no one can get the mail!
