If I bring down the vmware image, should I be able to immediately send emails to and from users that I have created from the zimbraAdmin? Or do I need to do more configuration?

I have created two users, and try to send a email from one to the another. I can log in successfully on both accounts and can see the email in the sent folder, but no mail arrivesin the other inbox.

I can see no errors in any of the logs in /opt/zimbra/log

where else should I be looking?
