Answer 1

You have to use smtp settings to be able to send the mail as most hosting providers now have closing the php mail function due to security reasons, this is the script for a proper smtp mail function and dont use third party tools like php mailer just ask your hosting provider to activate mail function in pear packages

<?php
require_once "Mail.php"; 
$from = "Web Master <[e-mail]>"; 
$to = "Nobody <[e-mail]>";
$subject = "Test email using PHP SMTP

";
$body = "This is a test email message";
$host = "SMTPhostname"; 
$username = "[e-mail]"; 
$password = "yourPassword"; 
$headers = array ('From' => $from, 'To' => $to, 'Subject' => $subject); 
$smtp = Mail::factory('smtp', array ('host' => $host, 'auth' => true, 'username' => $username, 'password' => $password)); $mail = $smtp->send($to, $headers, $body); 
if (PEAR::isError($mail)) { 
echo("<p>" . $mail->getMessage() . "</p>"); }
else
 { echo("<p>Message successfully sent!</p>"); 
} 
?>
