[ZendTo] Recipient Pickup Identification

Sorry for the late reply, I was on vacation when I saw this and just got around to looking at this, I didn't actually change since this code is exactly what my NSSDropbox.php file had in it.

I think the issue is the EmailSenderAddress in the zendto.conf, this is where it has "'Admin deq at mydomain.com<mailto:deq at mydomain.com>'" (with my actual domain name) listed.  Any messages sent from the zendto server shows that it's from this address so ALL outgoing messages from all users show as coming from me.  However, the "Reply To" address is the address of the actual sender.  The example config shows using a blanket address (helpdesk at zend.to<mailto:helpdesk at zend.to>).

However, it appears that Michel Moore may have it figured out, per his message below.  Is it not possible to change this?

Thanks everyone!

Hi,



Less sure about the second question, but the answer to the first one can be found here:



http://zend.to/preferences.php



You need to amend EmailSenderAddress to change the email account.  It comes from that account always.  AFAIK you can't set it so that it comes from the user who added the drop off.



Cheers,



Matthew Moore

Dale,

The answer to your question about the address the email appears to come from may also imply that you have an old version of the "deliverEmail" function in /opt/zendto/lib/NSSDropbox.php.

Find the definition of that function in that file (search for "deliverEmail" and you should find a line saying something like
    public function deliverEmail(
If your version has 5 parameters like the updated version I'm including for you below, you can *probably* replace your version of that function with this one. But **MAKE A BACKUP COPY OF THE FILE FIRST!!!** in case it doesn't work.

Here's the current code for that function, if you choose to try replacing your existing copy of that function:
---CODE STARTS HERE---
/*!
    @function deliverEmail

    Send the $content of an email message to (one or more) address(es) in
    $toAddr.
  */
  public function deliverEmail(
    $toAddr,
    $fromAddr,
    $subject,
    $content,
    $headers = ""
  )
  {
    // If it contains any characters outside 0x00-0x7f, then encode it
    if (preg_match('/[^\x00-\x7f]/', $subject)) {
      $subject = "=?UTF-8?B?".base64_encode(html_entity_decode($subject))."?=";
    }
    if (preg_match('/[^\x00-\x7f]/', $fromAddr)) {
      $fromAddr = "=?UTF-8?B?".base64_encode(html_entity_decode($fromAddr))."?=";
    }
    if (preg_match('/[^\x00-\x7f]/', $this->_emailSenderAddr)) {
      $sender = "=?UTF-8?B?".base64_encode(html_entity_decode($this->_emailSenderAddr))."?=";
    } else {
      $sender = $this->_emailSenderAddr;
    }

    // Add the From: and Reply-To: headers if they have been supplied.
    if ($fromAddr!="") {
      $headers = sprintf("From: %s", $sender) . PHP_EOL .
                 sprintf("Reply-to: %s", $fromAddr) . PHP_EOL .
                 $headers;
    }

    // Add the MIME headrs for 8-bit UTF-8 encoding
    $headers .= "MIME-Version: 1.0".PHP_EOL;
    $headers .= "Content-Type: text/plain; charset=UTF-8; format=flowed".PHP_EOL;
    $headers .= "Content-Transfer-Encoding: 8bit".PHP_EOL;

    return mail(
              $toAddr,
              $subject,
              $content,
              $headers // JKF Commented out for now due to security concerns ,
              // JKF Commented out for now due to security concerns
              // '-f "'.$fromAddr.'"'
            );
  }

---CODE ENDS HERE---

Do not put the "CODE STARTS HERE" or "CODE ENDS HERE" lines into your NSSDropbox.php file.

You can run the command
    php -l NSSDropbox.php
to check the syntax of what you have just pasted in.
There's a chance your email client (or my email client or the list manager) may wrap the code above badly, thereby breaking it.

That version should make the recipient's email app have the sender's address in the "From:" and "Reply-To:" headers, which I think is what you are asking for.

BTW I am working on an update at the moment. The ZendTo code is done, but needs some more testing.
The installer is getting the most work. I've got it done for RedHat and CentOS versions 5, 6 and 7.
Ubuntu next.
I'm automating the whole thing, including all the PHP rebuilding, SELinux support, firewall support, everything.
And you can just have it run whatever bits of the process you want to, so no need to risk it damaging your carefully configured email setup or anything like that.
But if you run it on a blank server you've just installed RedHat/CentOS on, it will do everything needed except preferences.php and zendto.conf.

Cheers,
Jules.

Subject: [ZendTo] Recipient Pickup Identification



Morning all!



I'm hoping that you can help me with two things.



First, when an internal sender drops off a file, the notification message to the recipient doesn't show as coming from the sender.  It shows as coming from the administrator account.  Where is this configured?  One of the problems is that if there is a NDR or an out of the office email returned, it comes to the administrator account, it does not go to the internal person that dropped off the file.



Secondly, looking at a dropoff summary, where the information is listed on who picked up the file, everything looks good with the exception of the Recipient.  It always shows "%s" (sans quotes) instead of the name or email address of the recipient that picked up the file.  I'm guessing that variable isn't being filled in somewhere…



I'm on version 4.01 and I'm hesitant to upgrade as this works so beautifully (except for the two issues above ☺)



Thanks!



Dale
