RoundCube already uses 'Disposition-Notification-To' / 'Return-Receipt-To' in message headers for sender notification, it's the most common type used in MUA's.
Some MTA doesn't support DSN as far I know, like Exim. Another type of return receipt option in compose window can also confuse the users, I do not think it's a good idea to implement in RC...
Have you considered it as a plugin? Please see http://trac.roundcube.net/wiki/Doc_Plugins

Hi.
This is my first contact on this list and I would like to share with you this new "feature" :-)
I would like to suggest the "Confirm-Delivery" functionality to Compose window.
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).
All you (the client) need to do is: RCPT-TO: xxx@yyy.com NOTIFY=SUCCESS
To make it work on RC, I did this:
- on COMPOSE NEW MESSAGE screen, add a checkBox:
[ ] Confirm Delivery
in skins\default\templates\compose.html:
<td id="delivery-selector"> <roundcube:object name="deliveryCheckBox" form="form"id="rcmcomposedelivery" /> <label for="rcmcomposedelivery"><roundcube:label name="confirmdelivery" /></label>
</td> ---------
in program\localization\en_US\labels.inc:
... $labels['confirmdelivery'] = 'Confirm delivery'; ...
in skins\default\mail.css:
#priority-selector, #receipt-selector, #delivery-selector { padding-left: 30px; white-space: nowrap; }
in program\steps\mail\compose.inc:
function rcmail_delivery_checkbox($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; }
$OUTPUT->add_handlers(array( ... 'deliverycheckbox' => 'rcmail_delivery_checkbox', ... ));
- make sendmail.inc collects the user action on new checkbox:
program\steps\mail\sendmail.inc
if (!empty($_POST['_delivery'])) { $headers['Return-receipt-to'] = $from; }
- ask smtp server to generates "success delivery report" for this
message:
in program\include\rcube_smtp.php:
public function send_mail($from, $recipients, &$headers, &$body) { if (!is_object($this->conn)) return false; // we use this special header to know if this message requires delivery report $confirm_delivery = eregi("Return-receipt-to",$headers) ? "NOTIFY=SUCCESS":""; ... ... // set mail recipients foreach ($recipients as $recipient) { // here: if (PEAR::isError($this->conn->rcptTo($recipient,$confirm_delivery))) { ...
And that's it!!
Just for info: I used "Return-receipt-to" header because I saw it on messages sent by PegasusMail client. (when I check the "Confirm Delivery" checkBox in pegasus)
This software is just GREAT !! thanks!
