Got Zimbra Web interface working fine now, but I'm unable to connect any desktop client Clients that I'm trying to connect are Outlook and Thunderbird on Windows; and Evolution and Thunderbird on Linux.

When I try to connect the client I get a timed out error, Ive tried connecting using ports 143,993,7143 and 7993 with nothing. Both /var/log/messages and /var/log/zimbra.log show nothing, any ideas?
