OK. I give. For years and years and years everyone always references telneting to an Exchange Server for testing the SMTP. I have never been able to do it. I have a Windows 7 x64 box with telnet installed. I open a command prompt and type in "telnet mailserver 25" get the error that the connection could not be opened.
I am doing something wrong and have been for years because I have never been able to get teleneting to work to an Exchange Server. I have even tried with Putty. What am I doing wrong?
