I have 2 networks in my office. One has an exchange 5.5 and another has exchange 2003.
From my house I can not telnet to port 25 on any of the two servers.
If I telenet from a diferent location then my house it works fine.
Can it be my ISP blocking it? I have earthlink at home.
If so, is there a way to bypass that? And why would they do that?
