How does the configuration of the SMTP server affect the PHP mail() function in the context of the error message received?

If the SMTP server is not properly configured in the php.ini file, the PHP mail() function may not work correctly and could result in an error message such as "Failed to connect to mailserver." To solve this issue, ensure that the SMTP server settings in the php.ini file are correctly configured with the appropriate host, port, username, and password. 

// Set the SMTP server settings in the php.ini file
ini_set("SMTP", "mail.example.com");
ini_set("smtp_port", "25");
ini_set("sendmail_from", "email@example.com");

// Send an email using the PHP mail() function
$to = "recipient@example.com";
$subject = "Test Email";
$message = "This is a test email.";
$headers = "From: email@example.com";

mail($to, $subject, $message, $headers);
