We're having a problem and unable to send out email from a previously working IIS 6/SMTP instance on a Win2003 Server.
When I do the telnet test: PROMPT>telnet 188.8.131.52 25
I do not get a banner specifying the SMTP Server version and allowing me to continue to HELO.
The command shell is cleared and only a prompt remains. Further attempts at entering HELO or MAIL FROM: just send me back to the prompt.
IF SMTP is running in the services control panel why am I not able to do this?
