email form - convert from PHP to SMTP

Morning,

I have the following code on my site, when a user fills out a form, I post to a page with the following code. Pretty basic I know, however my host has disabled php mail on all it's servers for goodness knows how long.

My question is, How do I re-jig this code to work with SMTP instead ? (sorry, not very handy with PHP myself)

<?php

$ip = $_POST['ip']; 
$httpref = $_POST['httpref']; 
$httpagent = $_POST['httpagent']; 
$visitor = $_POST['visitor']; 
$visitormail = $_POST['visitormail']; 
$notes = $_POST['notes'];
$attn = $_POST['attn'];


if (eregi('http:', $notes)) {
die ("Do NOT try that! ! ");
}
if(!$visitormail == "" && (!strstr($visitormail,"@") || !strstr($visitormail,"."))) 
{
echo "<h2>Please click 'BACK' and Enter a valid e-mail</h2>\n"; 
$badinput = "<h2>Feedback was NOT submitted</h2>\n";
echo $badinput;
die ("Go back! ! ");
}

if(empty($visitor) || empty($visitormail) || empty($notes )) {
echo "<h2>Please fill in all the required (<FONT COLOR='RED'>*</FONT>) fields</h2>\n";
die ("Please click 'BACK' on your webbrowser and try again.<BR><CENTER><B>Your message has NOT been sent!</CENTER></B>"); 
}

$todayis = date("l, F j, Y, g:i a") ;

$attn = $attn ; 
$subject = $attn; 

$notes = stripcslashes($notes); 

$message = " $todayis [EST] \n
Attention: $attn \n
Message: $notes \n 
From: $visitor ($visitormail)\n
Additional Info : IP = $ip \n
Browser Info: $httpagent \n
Referral : $httpref \n
";

$from = "From: $visitormail\r\n";


mail("my_email@here.com", $subject, $message, $from);

?>

Code (markup):

Thanks for any and all help.
