Telnet an e-mail message

To send an e-mail to a mail-server use the following commands:

Telnet <hostname_of_mailserver> 25

HELO <your_domain_name>

MAIL FROM: <yourname>@domainname.tld

RCPT TO: <e-mailaddress@where.you.want.to.send>

DATA

<enter your message>

.<enter>

QUIT

The e-mail server should send the message out. Normally (to block relaying) the server will only send e-mails from your own domain!
