This question has been answered many times in the forums and is covered in a wiki article, if you behind a NAT router then you'll need a Split DNS set-up.

I'm also setting up an Ubuntu 10.04 server with Zimbra 7.1.2 and while I'm doing this, I am documenting each and every little step....including the split-dns configuration.
