> TELNET mail.somedomain.com
< 220 mail.somedomain.com...
> HELO thisis.mydomain.com
< 220 ...
> MAIL FROM: <[EMAIL PROTECTED]>
< 220...
> RCPT TO: <[EMAIL PROTECTED]>
At this point, you'll get a message either saying "OK" (which means that
the mail server will accept mail for the user, but that doesn't necessarily
mean it will be delivered), or a message explaining why it will not be
delivered.
You can use the "VRFY <[EMAIL PROTECTED]>" command (instead of the MAIL
FROM and RCPT TO), but many systems disable that.
