The PHP mail function is used to send emails from a PHP script. If an error occurs while trying to send an email using the mail function, it is usually logged in the PHP error log file.
The location of the PHP error log file is specified in the error_log setting in the PHP configuration file (usually php.ini). The default location of the error log file is usually /var/log/php_errors.log or /var/log/httpd/error_log, but it may vary depending on your PHP installation and operating system.
You can view the PHP error log file using a text editor or by using the tail command in a terminal. For example:
tail -f /var/log/php_errors.logSource:wl.wwautturi.com
This will display the contents of the PHP error log file in the terminal as new errors are logged.
It's important to note that the location and name of the PHP error log file may vary depending on your PHP installation and operating system. Consult the PHP documentation and your system's documentation for more information.
