I needed to create a script today that takes raw SMTP input from stdin. The project is running on Zend and they have a library for email. However, their documentation is geared toward getting that email from a mailserver. As far as I could find there wasn’t an example of how to create an email object out of the raw SMTP data.

Create a Zend_Mail_Message from the raw string.

$email = new Zend_Mail_Message(array('raw' => $email_str));

To grab the subject:

$email->subject;

All I wanted was the body from the text/plain piece of the email. If you’ve got a multi-part message it’s a little tricky. Here’s what I compiled from Zend’s documentation:

if($email->isMultipart()) {
  foreach (new RecursiveIteratorIterator($email) as $part) {
    try {
      if (strtok($part->contentType, ';') == 'text/plain') {
        $body = trim($part);
        break;
      }
    } catch (Zend_Mail_Exception $e) { // ignore }
  }
  if(!$body) {
    //Error
  }
} else {
  $body = trim($email->getContent());
}
