This is some old info I found and thought it still my be handy. I will update more about how to install Telnet and refine this up a bit but wanted to throw it up here so I did not forget. I also want to test to see if it still works which I think it should unless TLS is the ONLY way now.

  • Open command prompt 
  • find the mx record for the domain
    • Nslookup 
    • set type=mx 
    • Americanrampcompany.com 
    • exit 
  • after that telnet to the mx record name on port 25.  (if you press backspace and enter a command the command will fail.  You must enter it correctly the first time with no backspaces)
    • telnet mail.example.com 25 
  • type a hello message
    • ehlo mail.example.com 
  • if that does not work try
    • helo mail.example.com 
  • Enter the from email address you want to use
  • Enter the to email address.  (Use a valid address)
  • Type the follow to let the server know you are going to send some data
    • DATA 
  • now type the subject then press enter twice
    • subject: Test Message 
  • Type in the body
    • this is a test message you will not see a response from this command. 

 After the body message press enter then type . (period) and then press enter again so it knows you are done with the body 

  • The email should have sent
    • quit
