Multiple page form to email with sessions doesn't send mail

Question

I am creating a multiple page form where a user can apply for finance. I am trying to use session to keep the user input values and then the last page sent the application by email.
My problem is the last step where it doen't send the email. I'm not sure if it the session I'm using is wrong because a simple form without sessions works fine.
here are the forms
First page is the input for with variables
<form action="Finance_form_proposal_Address.php" method="post" >
  <span id="sprycheckbox1">
  <input  name="Disclaimer" type="checkbox" value="yes">
  <span class="checkboxRequiredMsg">Please confirm that you have read and understood the Terms and Conditions.</span></span>
  <div id="F1"><table width="100%" border="1" align="center" cellpadding="3" cellspacing="2">
  <tr>
    <td align="right" bgcolor="#F7E4F8" ><strong>Title:</strong></td>
    <td align="left" bgcolor="#F7E4F8"><select name="Title">
          <option value="Mr">Mr</option>
          <option value="Mrs">Mrs</option>
          <option value="Miss">Miss</option>
          <option value="Ms">Ms</option>
          <option value="Dr">Dr</option>
          <option value="Rev">Rev</option>
        </select></td>
etc..
</form>
The second form:
Getting values and input new form
<?php session_start();
$_SESSION['Disclaimer'] = $_POST['Disclaimer'];
$_SESSION['Title'] = $_POST['Title'];
$_SESSION['Forname'] = $_POST['Forname'];
$_SESSION['Middle_name'] = $_POST['Middle_name'];
$_SESSION['Surname'] = $_POST['Surname'];
$_SESSION['email'] = $_POST['email'];
$_SESSION['DOB'] = $_POST['DOB'];
$_SESSION['DOB2'] = $_POST['DOB2'];
$_SESSION['DOB3'] = $_POST['DOB3'];
$_SESSION['Gender'] = $_POST['Gender'];
$_SESSION['checkboxGroup1'] = $_POST['checkboxGroup1'];
$_SESSION['checkboxGroup2'] = $_POST['checkboxGroup2'];
$_SESSION['home_phone'] = $_POST['home_phone'];
$_SESSION['mobil'] = $_POST['mobil'];
$_SESSION['marital_status'] = $_POST['marital_status'];
$_SESSION['Occupancy'] = $_POST['Occupancy'];
$_SESSION['Dependants'] = $_POST['Dependants'];
?>
Form on second page
<form action="Finance_form_proposal_Bank_Details_employment.php" method="post"> <input  name="Disclaimer" type="checkbox" value="yes">
    <div id="F1"><table width="100%" border="1" align="center" cellpadding="3" cellspacing="2">
  <tr>
    <td align="right" bgcolor="#F7E4F8" ><strong>Correspondence Address:</strong></td>
    <td align="left" bgcolor="#F7E4F8"><input name="Correspondence" type="checkbox" id="Correspondence" value="yes" checked="CHECKED">
      <label for="Correspondence"></label></td>
  </tr>
  <tr>
    <td bgcolor="#F7E4F8"><strong>Street:</strong></td>
    <td bgcolor="#F7E4F8"><input name="Street" type="text"></td>
  </tr>
  <tr>
    <td bgcolor="#F7E4F8"><strong>District:</strong></td>
    <td bgcolor="#F7E4F8"><input name="District" type="text"></td>
  </tr>
  <tr>
    <td bgcolor="#F7E4F8"><strong>Town:</strong></td>
    <td bgcolor="#F7E4F8"><input name="Town" type="text"></td>
  </tr>
etc ..
</form
Third page
Getting values
session_start();
$_SESSION['Correspondence'] = $_POST['Correspondence'];
$_SESSION['Street'] = $_POST['Street'];
$_SESSION['District'] = $_POST['District'];
$_SESSION['Town'] = $_POST['Town'];
$_SESSION['County'] = $_POST['County'];
$_SESSION['Country'] = $_POST['Country'];
$_SESSION['Years'] = $_POST['Years'];
$_SESSION['Months'] = $_POST['Months'];
$_SESSION['Street2'] = $_POST['Street2'];
$_SESSION['District2'] = $_POST['District2'];
$_SESSION['Town2'] = $_POST['Town2'];
$_SESSION['County2'] = $_POST['County2'];
$_SESSION['Country2'] = $_POST['Country2'];
$_SESSION['Years2'] = $_POST['Years2'];
$_SESSION['Months2'] = $_POST['Months2'];
$_SESSION['Street3'] = $_POST['Street3'];
$_SESSION['District3'] = $_POST['District3'];
$_SESSION['Town3'] = $_POST['Town3'];
$_SESSION['County3'] = $_POST['County3'];
$_SESSION['Country3'] = $_POST['Country3'];
$_SESSION['Years3'] = $_POST['Years3'];
$_SESSION['Months3'] = $_POST['Months3'];
Then there is a another form to fill in , wont show that as it is in principle the same.
This is the last page that should sent the data to email:
<?php
session_start();
/* Subject mail variables */
$emailsubject = 'Finance application from PandKshop';
$webmaster = '[email protected]';

$Sort_Code          = $_SESSION['Sort_Code'];

Is there something wrong with my sessions or just something in the code?

Answer 1

Standard Apple Mail. I'm running Yosemite 10.10.1, and I'm amazed to see that About Mail says it's Mail Version 8.1 (1993), copyright 1995-2014 Apple Inc. 
Interesting thought, do you think that it doesn't like to work with itself?  Actually, I'm fairly sure I've had the problem inside of other apps but I should document that.  I'll keep notes to see where this happens.
