Port Seems to be blocked!

As Mike Flasko asked in a comment and I suspected yesterday but didn't get around to checking; it looks like my pc here can't connect via SMTP to Gmail. I attempted with telnet, and receive the same error that .net reported. May be I can find some time today to try System.Net.Mail with the exchange server here.

# re: My firewall needs some ruffage.

I think that Gmail only opens port 465 for smtp *relay* on smtp.gmail.com (I think) and you have to access it SSL.

I think that port 25 on smtp.gmail.com is for local delivery - but I could be mistaken.

Additionally, some ISP's will block port 25 outbound except to their outbound smtp servers.
