PHP form keeps getting filtered, needs adjusting

[volcomp]

This PHP form keeps getting blocked by a filter... I think I need a legimate (sender) email address and not a undefined one... but I don't know how to adjust this php address... help!


<?php
$ToEmail = "$Email";
$ToSubject = "$FirstName thought you might be interested";
$EmailBody = "\n\n$FirstName thought you may be interested in our Resturant. Please visit the website at <a href="http://www.resturantname.com" target="_blank">www.resturantname.com</a> and remember to enter into our monthly dinner for two contest. A fine dinning experience valued up to blank dollars.\n";
$EmailFooter="\n\nIf you feel that you have received this e-mail by accident please contact us at info@resturantname.com\n\n";
$Message = $EmailBody.$EmailFooter;
mail($ToName." <".$ToEmail.">",$ToSubject, $Message, "From: ".$FirstName." <".$Email.">");
?>



Thanks
