My ISP has port 25 blocked. I tried using Hotstop Shield to get around it, but the server identifies the proxy as spam'er. Where do I go from here?

There's no need to use a proxy. You can connect to Hotmail's mail server using the well-known port 587 (e-mail message submission).

Your ISP shouldn't block port 587, since it's intended specifically to submit a mail to a mail submission agent. Meanwhile, connections to port 25 could be used to send spam directly from your computer.

Also blocked. Just tried to connect. –  OscarFR Jan 16 '13 at 3:34
    
I went to a website which checks for open ports and it seems to be unreachable. –  OscarFR Jan 16 '13 at 3:38
    
That's odd, since there's no good reason to block connections to port 587. Which website? –  Dennis Jan 16 '13 at 3:38

That site checks for open machines on your machine. You have to connect to Hotmail's mail server using and outgoing connection on their port 587. That's entirely different. Just try telnet smtp.live.com 587. –  Dennis Jan 16 '13 at 3:42
