(via Telnet port 25 or port 587) with Windows XP, Windows Vista. If you run a different operating
system then Microsoft Windows please check other sources on the Internet.

command.

Note There are different versions of Microsoft SMTP or third party SMTP servers, and you may receive different responses from the receiving server. What is important is that you receive the 220 response
In case your ISP does not allow SMTP connections, you will receive an error message
or a timeout.
