How can PHP developers ensure that email notifications are sent successfully when using the mail() function, especially when dealing with email addresses containing a dot before the @ symbol?

When using the mail() function in PHP to send email notifications, developers may encounter issues with email addresses containing a dot before the @ symbol. To ensure successful delivery, developers can use the double quotes around the email address in the mail() function to properly handle addresses with dots. 

$email = "john.doe@example.com";
$subject = "Test Email";
$message = "This is a test email.";

// Use double quotes around the email address to handle dots
mail("\"$email\"", $subject, $message);
