The error logs generated by the mail() function in PHP can be found in various locations, depending on the operating system and configuration of your system. Here are some common locations where the error logs may be stored:
/var/log/mail.logor/var/log/syslog: On many systems, the error logs generated by themail()function will be stored in either the/var/log/mail.logor/var/log/syslogfile. These logs will contain information about any errors that occurred during the sending of an email using themail()function.- Apache error logs: If you are using Apache as your web server and PHP is configured as an Apache module, the error logs generated by the
mail()function may be stored in the Apache error logs. The location of these logs will depend on your Apache configuration, but common locations include/var/log/httpd/error_logor/var/log/apache2/error.log. - PHP error logs: If you have configured PHP to log its own errors, the error logs generated by the
mail()function may be stored in the PHP error logs. The location of these logs will depend on your PHP configuration, but the default location is/var/log/php_errors.log.
If you are unable to find the error logs generated by the mail() function, you can check the PHP configuration file (usually located at /etc/php.ini) for the location of the error logs. If the error logs are not being generated, you can try increasing the verbosity of the error logs by setting the error_reporting value in the PHP configuration file.
