Are you receiving emails from your site outside the forums? If not or if unknown create page called email.php. In it paste this

PHP Code


<?php
$to = "someone@example.com";
$subject = "Test mail";
$message = "Hello! This is a test email message.";
$from = "someonelse@example.com";
$headers = "From:" . $from;
mail($to,$subject,$message,$headers);
echo "Mail Sent.";
?>

Change the "$to" adding your email address. Upload it to your web directory and go to www.yoursite.com/email.php. If successful you will see Mail sent and get the email.

If you don't get this, who's your host? Have access to mail error logs?
