No Email Problem after successful install
Here is a post by another member that seems to have fixed the problem.
In addition, I urge everyone to start by looking at the Bug Tracking posts; there are minor misspelling and other more major issues that will help you clean up osTicket 1.6RC3, until a newer version is available.

I must thank Peter, the developer of osTicket, for the great job he has done and is doing, and everyone who is using this forum for sharing information. This is truly a great product equal to the best commercially available products. It behooves all of us to cooperate in helping out through this forum to ensure that we end up with a stellar product.
