(PHP Extension) Create DSN (Delivery Status Notification) EmailDemonstrates how to create a DSN (Delivery Status Notification) Email having the format as defined in RFC 3464.
<?php // The version number (9_5_0) should match version of the Chilkat extension used, omitting the micro-version number. // For example, if using Chilkat v9.5.0.48, then include as shown here: include("chilkat_9_5_0.php"); $email = new CkEmail(); // A DSN email is a report about the attempt to delivery // an email. It is usually a report that indicates failure or // or a delay in delivery. The DSN is typically sent back to // the sender of an email. // IMPORTANT: // Note: Please be careful in sending automated DSN's. // It is important to be aware of an issue called "backscatter". // See the Wikipedia article here: http://en.wikipedia.org/wiki/Backscatter_%28e-mail%29 // The CreateDsn method will be called to create a new // DSN email based upon the email object calling CreateDsn. // The email object instance used to call CreateDsn would // typically be an email received from a POP3 or IMAP server. // In this case, to simplify the example, we'll load the email // from a .eml file. // This example will be creating a DSN for "someEmail.eml" $success = $email->LoadEml('someEmail.eml'); if ($success != true) { print $email->lastErrorText() . "\n"; exit; } // The DSN created by CreateDsn will contain a // "message/delivery-status" MIME sub-part that will // be composed of a number of name-value pairs. // See RFC 3464 ( http://tools.ietf.org/html/rfc3464 ) // The name-value content for this part is passed // as XML to CreateDsn. This part of the example // prepares the XML: $xml = new CkXml(); // For this example, we're just adding a few name-value pairs. // These should not be considered to be correct, required or // even sensible -- it's simply for the example. $xml->put_Tag('DeliveryStatusFields'); $xml->NewChild2('Status','5.1.2 (bad destination system: no such domain)'); $xml->NewChild2('Diagnostic-Code','smtp; Permanent failure: no such domain'); $xml->NewChild2('X-BounceCategory','bad-domain'); $xmlStr = $xml->getXml(); // The last argument to be passed to CreateDsn will be a boolean // indicating whether to include the entire MIME of the calling // email object in the DSN, or only the header. // It may make sense to include the entire email for small emails, // but for large emails (with large attachments) it's probably // best to make the DSN header-only. $bHeaderOnly = true; // The first argument to be passed to CreateDsn will // be a human-readable explanation that will be placed // into the 1st MIME part of the DSN (see RFC 3464). $humanReadableExplanation = 'Blah blah blah. The delivery of this email failed. Blah blah blah'; // OK, we're ready to create DSN.... // dsnEmail is a CkEmail $dsnEmail = $email->CreateDsn($humanReadableExplanation,$xmlStr,$bHeaderOnly); if ($email->get_LastMethodSuccess() == false) { print $email->lastErrorText() . "\n"; exit; } // Show the MIME of the source (original) email: print $email->getMime() . "\n"; print '**************************************' .
