We have 2 types of users in the organization, one who can send external emails other who cannot. How can I block users from sending emails to domains other then what they belong to? I have an option of using CPanel as SMTP relay and actual mailboxes are hosting somewhere else. So both option can work for me if I get an option to block certain users or I can block all users using "1" SMTP gateway to not able to send emails to external domains.
Hello @umar_rana,
You could setup a custom Exim system filter rule to prevent email users from sending to remote domains. Here are a couple of threads with examples you may find useful:
Blocking all cPanel users from emailing specific domains/email accounts
Need to filter ALL email
Thank you.
