Prevent a cpanel user from sending email entirely?

[M001]

Hi guys,

I just want to stop a certain user from being able to use my exim server. Is there something simple I can add to config file or set this in WHM?

Move the domain entry from /etc/localdomains to /etc/remotedomains

Obviously would apply to all users of the domain.

Obviously would apply to all users of the domain.

And if we want only One user of a domain, should we use the above process as well?

Hello,

Yes, you can also use ConfigServer Mail Manage (cmm) to mange the mails.

Sorry, I'm confused. How would I do it via their username? The reason I don't want to do it via domain is because i'm trying to limit a user who constantly has insecure wordpress files and his account is sending spam from "[email protected]" instead of his own domain. I would not want to block emails for my domain by adding my.server.name.com to that file, right?

Changing the domain's MX is Not going to prevent the account from sending Email.
Are you aware of the new Mail-features available under WHM > Modify Account? Use that.

Maximum Hourly Email by Domain Relayed unlimited (default)
Maximum percentage of failed or deferred messages a domain may send per hour unlimited (default)

Hello

You could disable all PHP mail on the server or for specific accounts by using the php.ini file. You can do this globally by adding "mail" to "disable_functions =" in /usr/local/lib/php.ini or for a single account using the path directive at the bottom of the php.ini file.

[PATH=/home/username/public_html]
disable_functions = mail

Thank you.

[PATH=/home/username/public_html]
disabled_functions = mail

I believe it should be:

[PATH=/home/username/public_html]
disable_functions = mail
