Need some SMTP troubleshooting help - Please!.

[Charles Jones]

Just thought I would mention that I know someone whose mail client was 
malfunctioning (trying to login with the wrong password over and over), 
and their IP was blocked with the same symptoms that you have. Is there 
any chance that you did something to trigger their IPS? If so then the 
solution is to just wait for the rule to expire :)
