Telnet – SMTP Commands (sending mail using telnet)

In order to access your mailbox you will need 3 things:

• An active internet connection (an embarrasing stage to miss sometimes!)
• The address of a mail server capable of relaying for you – usually provided by your dialup provider (e.g. mail.domain.ext)
• A valid email address (e.g. mail@domain.ext)

The first thing to do is to open a connection from your computer to your mail server.
