Telnet SMTP connection test
Testing the SMTPG connection to your mail server need not be difficult. This is what I usually do to test my mail servers’ SMTP status.
Telnet SMTP connection test
Open the command prompt. Use the following command.
telnet <smtp server’s name or IP Address> 25
You will the receive the SMTP server’s welcome screen.
Enter word helo . This will initiate the session.
Introduce yourself to the SMTP server by using the mail from: command.
mail from: <your email address on the domain>
Then, specify where you want to send the email to by using the rcpt to: command.
rcpt to: <receipient’s email address>
Next is to enter some message. Use the data command.
After completing your message, type “.” on a line by itself and enter. As per the diagram below.
The SMTP mail server will then generate the mail id and send the email. To end the session, type quit.
That’s how simple it is to troubleshoot if your mail server is serving your emails or not.
