hi,

The mass mailing in CiviMail (CiviCRM 4.6.2) using Mandrilla SMTP service does not handle error mails.
The problem to 2 causes in EmailProcessor.php :
Regular Expression search in headers X-Bounce-CiviMail while header set in the mail is X-Civimail-Bounce (small m)!!
Can be bypassed by an case insensitive search (/ i at the end of the regular expression).
    // a regex for finding bound info X-Header
    $rpXheaderRegex = '/X-CiviMail-Bounce: ' . preg_quote($dao->localpart) . '(b)' . $twoDigitString . '([0-9a-f]{16})@' . preg_quote($dao->domain) . '/i;
    // CiviMail in regex and Civimail in header !!!
Errors are returned in a multipart mail, and the part containing the header X-Civimail-Bounce, generated by $ mail-> generateBody, is base64 encoded.
One possible workaround is to look for parts of type ezcMailFile and search on the file content of this part.

if (!$matches and preg_match($rpXheaderRegex, $mail->generateBody(), $matches)) {
            list($match, $action, $job, $queue, $hash) = $matches;
          }
         
          // Code added +++++++++
          // With Mandrilla, the X-CiviMail-Bounce header is produced by generateBody
          // is base64 encoded
          // Check all parts
          if (!$matches) {
            $all_parts=$mail->fetchParts();
            foreach ($all_parts as $k_part => $v_part) {
              if ($v_part instanceof ezcMailFile) {
                $p_file = $v_part->__get('fileName');
                $c_file=file_get_contents($p_file);
                if (preg_match($rpXheaderRegex, $c_file, $matches)) {
                  list($match, $action, $job, $queue, $hash) = $matches;
                }
              }
            }
          }
          //  +++++++++
          // if all else fails, check Delivered-To for possible pattern

Theses changes are made in CiviCRM 4.6.2 and now bouncing work like a charme (in Mandrilla and in CiviCRM).

Hope this can help.
