Now here are three variables which are my final obstacle to getting Exchange Email to all users in all locations.
1. Smtp ports are blocked by some ISP in US and in China
2. VPN can connect shared drives but not to Exchange because the ports are blocked on the ISP Router
3. China is very regulated and hate Americans asking questions about what is blocked or not blocked. The ISP's are government run businesses in China is what i being told by users living there six months out of the year.
So how do I get users to connect to Exchange 2003 Server running on Ent. Server 2003 and we have the RAS server for VPN. Any suggestions.
I can test the solution here on myself with using Comcast connection which blocks smtp server relay
