List of useful commands to manage Exim mail server

The mail server installed on your HostPapa VPS is called Exim. While the mail server doesn’t require much interaction for sending or receiving average volumes of email, there may be times when you need to manage Exim’s settings.

Begin by logging in to your server in a terminal client using Secure Shell (SSH). Use the following Exim commands to manage your mail server.

exim -bpc
