I tried using Gmail Account configuration, have checked IMAP enable, but Zimbra always telling me to check that I have enable IMAP, mail address and password, all checked but cant connect.

This is under Ubuntu Hardy amd64, installation went fine only this one show stopper, used to work when I use Zimbra Destkop in my old computer.

Zimbra desktop version 0.90 build 1278

Thanks in advanced
