Works on home computer but not on another


I chanced across smtp4dev ... seems an excellent tool to check my email related code.

But it works only on my home computer.

It can execute on my machine @ work, (windows XP or Windows 7) desktop, I mean the window come up but

telnet localhost 25 or a telnet machine-name 25


However a telnet on my home PC, works okay.

What permissions of firewall settings could I be missing on my machine @ work
thank you.
