PHP mail() function is disabled server wide in order to prevent spam users from emaling.
When this function is blocked, emails from legit users are also blocked. Really sorry for that
In such cases, website owners configure their sites to send mail through the SMTP port instead of the PHP mail() function.
For wordpress websites, plugins and modules such as “WP Mail SMTP” for WordPress need to set up.
WARNING: If your site is using php mail() function to send emails, please ensure that you switch to smtp or otherwise your emails won't be delivered to your end users.
