We can't reset the password on login (if the password was forgotten), without getting this error.

How can we fix this? Any suggestions?

Thank you so much =)

Hi,

"Forgot password" uses PHP’s built-in `mail()` function to send email notifications. The `mail()` function relies on the server’s underlying mail system, such as `sendmail` or `postfix` on Linux, or SMTP settings configured in `php.ini` on Windows. It takes the recipient, subject, message body, and optional headers as input, and returns `true` if the message was accepted for delivery. However, this does not guarantee the email was actually delivered—it only confirms that it was handed off to the mail system.

If the `mail()` function fails (returns `false`), first ensure that error reporting is enabled in PHP so you can catch any syntax or configuration issues. Confirm that a valid `From` header is included, as many mail servers will reject emails without one. Check the server’s mail logs (e.g., `/var/log/mail.log` or `/var/log/maillog`) to see if the message was blocked or dropped. Also verify that the server has a working mail agent and that DNS records like SPF and DKIM are properly configured for the sender domain. For more robust error handling and delivery tracking, consider using a library like PHPMailer or routing email through a trusted SMTP provider.
