[RndTbl] Shaw blocking port 25 on business line

[Gerald Brandt]

So, port 25 opened for a few days. Shut down again today with no reason why.

Talked to business support, and they suggested that perhaps someone 
discontinued receiving our newsletter.

What the hell that has to do with SMTP out not connecting to any 
servers, I have no idea. That as stupid as saying since gmail can send 
to gmail, port 25 is open.
