To configure an outgoing SMTP server on a computer, here are the steps to follow:
1. Choose the SMTP server software you want to use. Some of the common software are Postfix, Exim and Qmail.
1. Install the SMTP server software on the computer.
1. Open the SMTP server software configuration file (usually called “main.cf” for Postfix) and configure the following settings:
- The name of the outgoing SMTP server
- Ports to use for outgoing connections (usually port 25 for standard SMTP protocol or port 587 for SMTP protocol with authentication)
- Authentication information (if you need to authenticate your outgoing SMTP server)
1. Restart the SMTP server software for the configuration changes to take effect.
1. Verify that the outgoing SMTP server is working correctly by sending an email from an email client (for example, Outlook or Thunderbird) using the configuration settings you have made.
