Thanks for the response. I will contact them and ask about that. Do you know why solution 1 works? Is it because I already have an existing IPSEC connection? Site 1 is 192.168.1.x and site 2 is 192.168.2.x. I've come to the conclusion that the other situation with my work PC only worked because I had already logged on the domain before I disconnected and when I reconnected via dialup and then VPN, it recognized me. At home, the VPN connection does not allow me to use the networks Internet connection, which is actually a good thing. And yes, all this fuss for one email connection, but it is an important one, nonetheless. Number 2 and 3 sound somewhat similar. I was using the cable company's mail server with authentication and it was working. Sigh.......
