creo que podrias usar la funcion mail()
$myname = "Me Myself";
$myemail = "myself@email.com";
$contactname = "Mister Contact";
$contactemail = "contact@email.com";
$message = "hello from happy me";
$subject = "A mail not refused by Hotmail";
$headers .= "MIME-Version: 1.0rn";
$headers .= "Content-type: text/html; charset=iso-8859-1rn";
$headers .= "From: ".$myname." <".$myemail.">rn";
$headers .= "To: ".$contactname." <".$contactemail.">rn";
$headers .= "Reply-To: ".$myname." <$myreplyemail>rn";
$headers .= "X-Priority: 1rn";
$headers .= "X-MSMail-Priority: Highrn";
$headers .= "X-Mailer: Just My Server";
mail($contactemail, $subject, $message, $headers);
