I can't seem to get this to work for me.  I can receive mail without any problems, but I cannot send.  I get following returned:

Delivery has failed on the enclosed message for the following reasons reported either by the mail delivery system on the mail relay host or by the local TCP/IP transport module:

550 not local host ***.com, not a gateway

I have blanked out the domain after my name...that was not done by the system.  Anyway, I'm pretty sure that port 25 is not blocked here.
