Tighten up your Exim (mail server)

For WHM versions 11.27/11.28

You may want to prevent users from bypassing your mail server to send mail. This feature allows you to configure your server so that the mail transport agent (MTA), Mailman mailing list software, and root user are the only accounts able to connect to remote SMTP servers.

To enable or disable users from bypassing your mail server:
Click Enable or Disable.


Please make sure that SMTP Tweak is turned on:

/scripts/smtpmailgidonly on

It’s also a good idea to require sender verification, which can be enabled in WHM >> Exim Configuration Editor
