Since we are in the field of cPanel server support, some of our clients have come with the requirement that they want to change the Email sending limit per domain.

You may have already know about the following option: Main –> Server Configuration –> Tweak Settings –> The maximum each domain can send out per hour

We recommend you to set it as low as possible. And then make per domain restrictions as below, to increase the numbers.

1. Login to your server
2. Edit /var/cPanel/maxemails
3. Add a new line saying “domain.com = increased_number” (eg: supportsages.com = 800)
4. Save the file.
5. And finally run /scripts/build_maxemails_config

And you are done!!!
