We no longer use port forwarding. If you want to move the tomcat port, there's a fair bit of info on that in the forums. You should shut down all the zimbra port forwarding, since it will break things, now. (This may be why you can't connect via tbird).

Thunderbird, I believe, will ask for a password based on how you set up the account - check your account settings.

If it won't connect, are you sure you're hitting the correct port? 143 for imap, 110 for pop.

When you installed, did you set the hostname of the zimbra service to curley.quirkservice.com? zmhostname will show this. If that's the case, then after login, you'll be redirected to that name, since that's the users mail host.
