I must have tried at least 10 ways of setting up the headers for this but nothing seems to work.

In my php.ini file, I have SMTP = 137.99.158.180 (my IP) and sendmail_from = [email protected] (some name I made up)

This is the form that I am using:
Code:
<form id="HowToForm" action="sendguide.php" method="post" name="HowToForm">
  <table id="FormTable" cellSpacing="2" cellPadding="2" width="700" align="center" border="0">
    <tr>
      <td align="middle"><font size="4">Your Name: <font color="red" size="5"><b>*</b></font></font><br>
        <input id="ConName" type="text" size="50" name="ConName">
      </td>
    </tr>
    <tr>
      <td align="middle"><font size="4">Your Email: <font color="red" size="5"><b>*</b></font></font><br>
        <input id="ConEmail" type="text" size="50" name="ConEmail" onBlur="this.value=ignoreSpaces(this.value);"><br>
        <i>This is to give credit to you for submitting your guide.</i>
      </td>
    </tr>
    <tr>
      <td align="middle"><font size="4">URL:</font><br>
        <input id="Address" type="text" size="50" name="Address"><br>
        <i>This is also to give credit to you for submitting your guide.<br>
        <b>[Vendetta] asks that you please <a href="javascript:popUp('linktoV.html')">link to us</a> on your website.</b></i>
      </td>
    </tr>
    <tr>
    <td align="middle"><font size="4">Your How-To Guide: <font color="red" size="5"><b>*</b></font></font><br>
        <textarea id="Guide" name="Guide" rows="18" cols="80"></textarea><br>
        <i>At this time, [Vendetta] does not and will not accept submissions as attachments. Please copy and paste into the box above.</i>
      </td>
    </tr>
    <tr>
      <td align="middle"><font size="4">Any additional comments/suggestions?</font><br>
        <textarea id="Comments" name="Comments" rows="5" cols="45"></textarea>
      </td>
    </tr>
    <tr>
      <td align="middle"><br>
        <input type="button" id="SubmitButton" value="Submit" name="cmdSubmit" onclick="verify);">&nbsp;&nbsp;&nbsp;<input id="ClearButton" type="reset" value="Clear" name="cmdClear">
      </td>
    </tr>
  </table>
</form>
Here's what I try to send:
PHP Code:
<?php 
/*************************************** 
** check to make sure ppl cannot spam ** 
***************************************/ 
if($sentemail == "5"){ 
include("HowTo_fail.html");  //displays page if spamming 
}else{ 
$num = $sentemail + 1; 
setcookie("sentemail","$num",time()+600); //set the cookie (expires in 10 minutes) 
/*************************************

*************************************/ 
$to = "[email protected]";
$mailheaders = "X-Mailer: PHP/" . phpversion();
$mailheaders .= "From: $ConEmail\n";
$subject = "[Vendetta] How-To Guide Submission";
$email = "The following How-To Guide information has been submitted:\n\nUser Name:\t$ConName\nUser Email:\t$ConEmail\nUser IP:\t$REMOTE_ADDR\nUser URL:\t$Address\nUser Comments:\t$Comments\n\nHow-To Guide:\n$Guide\n\n";
mail($to, $subject, $email, "From: [email][email protected][/email]); //sends mail
/***************************************

$to = $ConEmail;
$mailheaders = "X-Mailer: PHP/" . phpversion();
$mailheaders .= "From: $AdminMail\n";
$subject = "[Vendetta] How-To Guide Submission";

mail($to, $subject, $email, $mail_headers); //sends mail
/************************

*************************/ 
include("HowTo_thanks.html"); //sends user to customized thank you page 
}
?>
I don't understand what the problem is here. Everything should be working. Do I need to have my sendmail_from variable match my From header or something?
