How do you disable email sent from PHP with PHP-FPM?

[WebHostPro]

We have a server that wants to remove all email being sent from it. I disabled exim and IMAP but I can't find how to disable PHP email. I've scoured this forum for 20 minutes and give up lol.

Can someone post a cheat code of what file to edit and what to add to disable all PHP email when using PHP-FPM please?

I assume it's something to do with the file default_accounts_to_fpm

Maybe add this there?: disable_mail

Hello,

You'd just need to follow the instructions for modifying .ini values here: How to Manage Your php.ini Directives with PHP FPM | cPanel & WHM Documentation

I read that many times and it does not say anything about removing mail and the tutorial is confusing. Where is the examples?

I got as far as:

1. /var/cpanel/ApachePHPFPM directory if it does not already exist.
2. Create the /system_pool_defaults.yaml file.

In this file I'm supposed to add PHP-FPM pools.

Which it now says to go to this file for help : Configuration Values of PHP-FPM | cPanel & WHM Documentation

Which also does not have a examples. And it doesn't say anything about adding one for mail.

Can you even stop mail server wide or at least from PHP on the server?

I'm sorry I thought you understood how to disable PHP mail but just needed the instructions to do so with php-fpm. You need to add the following:

This uses:

disable_functions =

and the value for PHP mail is just "mail" so you'd just want to add mail to the appropriate file. The default for this with php-fpm as listed in the guide you linked looks like the following:

php_admin_value_disable_functions: exec,passthru,shell_exec,system

You'd change it to be:

php_admin_value_disable_functions: exec,mail,passthru,shell_exec,system

Then follow the instructions on changing this either globally or per domain as listed in the documentation I originally linked How to Manage Your php.ini Directives with PHP FPM | cPanel & WHM Documentation

I should of mentioned I was past that, sorry. This is perfect, thank you!

So the file should like this right:

disable_functions =

php_admin_value_disable_functions: exec,mail,passthru,shell_exec,system

 

[cPanelLauren]

in the default php.ini it looks like (only added this so you knew which section in the normal php.ini file it was) :

disable_functions =

If you want to change that or all of the PHP versions php.ini files in case you decide to disable php-fpm you'll make it look like:

disable_functions = mail

When modifying for php-fpm it looks like:

php_admin_value_disable_functions: exec,passthru,shell_exec,system

If you want to disable mail when running php-fpm you'll change the appropriate file to look like:

php_admin_value_disable_functions: exec,mail,passthru,shell_exec,system

This is for a server that uses PHPFPM

So I add to the file: /var/cpanel/ApachePHPFPM/system_pool_defaults.yaml

php_admin_value_disable_functions: exec,mail,passthru,shell_exec,system

Then reboot PHPFPM

Correct?

A bit more than that. You'll need to do the following (as noted in the documentation for making modifications both globally and per domain)

Rebuild the PHP-FPM configuration

usr/local/cpanel/scripts/php_fpm_config --rebuild

Restart PHP-FPM and Apache:

/usr/local/cpanel/scripts/restartsrv_apache_php_fpm
/usr/local/cpanel/scripts/restartsrv_httpd
