[oclug] Linux Server or PHP?

[Zhimmy Kanata]

Hi,
   
  I'm running into an interesting problem..Maybe its just me..
   
  But in the program below I have passed a $email into the mail() function. The server runs the function and its suppose to send a email to whoever is listed in $email...its running the function and delivers nothing!? I would have thought that if it wasn't running the function it would display and internal error message? So is it me..which I imagine it is or is it the server? Hmmm.... my code is listed below. If can anyone can help it would be apprecatied.
   
  <?php
  require("config.php");
require("functions.php");
  
//echo some styles to spice it up...
  echo "
<style>
body
   {   
   background: #131313;
