Confirm Delivery CheckBox on Compose New Message

[fms]

Hi There!

We successfully added the "Confirm-Delivery" functionality on ROUNDCUBE running on our server, and I would like to suggest RC team to incorporate it.

Scenario:
You want to send an e-mail and you need a way to confirm that your MAILSERVER delivered it successfull to the DESTINATION MAILSERVER.

Many MTAs implement "Succesfull Delivery Report" (POSTFIX for example).

To ask a MAILSERVER to generate this report for you, your smtp CLIENT must say to the smtp server:
   RCPT-TO: [email protected] NOTIFY=SUCCESS

To make it work on RC, we did this:

1) on COMPOSE NEW MESSAGE screen, we add a checkBox:   [  ] Confirm Delivery

in skins\default\templates\compose.html, we add:

Code Select Expand


     <td id=&quot;delivery-selector&quot;>
      <roundcube:object name=&quot;deliveryCheckBox&quot; form=&quot;form&quot; id=&quot;rcmcomposedelivery&quot; />&nbsp;<label for=&quot;rcmcomposedelivery&quot;><roundcube:label name=&quot;confirmdelivery&quot; /></label>
    </td>


in program\localization\en_US\labels.inc:

Code Select Expand


...
$labels['confirmdelivery'] = 'Confirm delivery';
...


and add "#delivery-selector" on skins\default\mail.css:

Code Select Expand


#priority-selector,
#receipt-selector,
#delivery-selector
{
  padding-left: 30px;
  white-space: nowrap;
}


in program\steps\mail\compose.inc:

Code Select Expand



// we add this new function:
function rcmail_delivery_checkbox($attrib)
{
  global $MESSAGE, $compose_mode;
 
  list($form_start, $form_end) = get_form_tags($attrib);
  unset($attrib['form']);
 
  if (!isset($attrib['id']))
    $attrib['id'] = 'delivery';  

  $attrib['name'] = '_delivery';
  $attrib['value'] = '1';
  $checkdelivery = new html_checkbox($attrib);

  $out = $form_start ? "$form_start\n" : '';
  $out .= $checkdelivery->show(in_array($compose_mode, array(RCUBE_COMPOSE_DRAFT, RCUBE_COMPOSE_EDIT))
&& $MESSAGE->headers->mdn_to ? 1 : 0);
  $out .= $form_end ? "\n$form_end" : '';

  return $out;
}

$OUTPUT->add_handlers(array(
...
// we add this line:
  'deliverycheckbox' => 'rcmail_delivery_checkbox',
...
));


2) make sendmail.inc collects the user desire for this message:

program\steps\mail\sendmail.inc

Code Select Expand


if (!empty($_POST['_delivery']))
  {
  $headers['Return-receipt-to'] = $from;
  }



3) we want tell smtp_server to generate success-delivery-report for this message:

in program\include\rcube_smtp.php:

Code Select Expand


  public function send_mail($from, $recipients, &$headers, &$body)
  {
    if (!is_object($this->conn))
      return false;

//we add this:
$confirm_delivery = eregi("Return-receipt-to",$headers) ? "NOTIFY=SUCCESS":"";
...

...
// we add the $confirm_delivery parameter on rcptTo call
    // set mail recipients
    foreach ($recipients as $recipient)
    {
// here:
      if (PEAR::isError($this->conn->rcptTo($recipient,$confirm_delivery))) {
...


And that's it!!

Just for info:
We used "Return-receipt-to" header because we saw it on messages sent by PegasusMail client.
(when we check the "Confirm Delivery" checkBox in that message)

I hope ROUNDCUBE team accept my suggestion and include this great feature in RC.

Best regards
