Sites not sending email unless php-fpm is enabled?

[ttremain]

Strange thing.

Multiple sites stopped sending emails. An example error message from WP and Gravity forms was "WordPress was unable to send the notification email. Could not instantiate mail function." This goes away if php-fpm is enabled on the account.

Some setting I'm missing somewhere?

A secondary issue, is if we need PHP-FPM it seems it can only be enabled from root WHM. cPanel users show the option crossed out.

So many problems I'm seeing with PHP-FPM, it doesn't sound worth the headache, but right now we have a headache without it.

Hey there! As a test, are you able to view a PHP info page, or other PHP content on the domain when php-fpm is disabled?

info page, and other PHP content, yes...

WordPress appears to be working but then cannot send the email, and sticks it in a PHP based queue instead.

Do you happen to have a file at /var/cpanel/ApachePHPFPM/system_pool_defaults.yaml on the server?

Just for fun, can you rename that file so it can't be read by the system, restart the service, and see if that gets the mail working?

mv /var/cpanel/ApachePHPFPM/system_pool_defaults.yaml /var/cpanel/ApachePHPFPM/system_pool_defaults.yaml.bak
/scripts/restartsrv_apache_php_fpm
