VPS hosting and Dedicated Server hosting have the ability to modify exim port using WHM. Many ISPs (Internet Service Providers) block port 25. It is advantageous to have an alternate port that is available to use to prevent interruption when sending out emails. For example, setting the port 26 (465 or 587) to be available for usage:
- Log in to WHM.
- Click on Service Configuration
- Click on Service Manager.
- Under exim, enable the SMTP Server.
- Under exim on another port, make sure the port is set to 26.
- Click Save.
