How to view and send email using telnet

For troubleshooting email problems with HostPapa VPS hosting plans, it can be helpful to view and send email directly on the server via telnet.

Before you begin

The telnet client application is not installed by default on VPS servers. If you haven’t already installed it, log in to your server via SSH and run the following command:

yum install telnet
When the installation is finished, you’ll see a Complete! message.

Sending email via telnet

Note: In each example, replace mydomain.com with your domain name.

From a command prompt on your local computer, enter the following command to connect to your server on port 25, which is used for outgoing email:

telnet mydomain.com 25

Now type helo to begin communicating with the mail server:

helo

Next, enter your email address:

mail from: myemail@mydomain.com

Enter the recipient’s email address:

rcpt to: user@gmail.com

To write the email message, type data, then the subject and message body. To end the email message, type a period (.) on a line by itself and press Enter:

Subject: Test email

Hi,

This is a test message.

Regards,
Me
