How to test if a machine has access to the smtp server

This url: http://support.microsoft.com/kb/304897
helps us in testing if server
is allowed to relay etc..

Basically you do:
1. telnet servername port
2. EHLO
3. RSET

(YOU SHOULD SEE MESSAGE AS A RESULT:
250 2.0.0 Resetting)

4. MAIL FROM:UserName@DomainName.com
(use an email belonging to the domain)

5. RCPT TO:RecipientName@DomainName.com
(use email belonging to the domain)

6. QUIT (TO EXIT)

Above should send out an email without errors.
This should tell us if we can configure email
properly.
