Sending base64 emails using SWIFTMAIL

Question

I'm just trying to get my multi-page base64 encoded emails and send via swiftmail. Here is the code that I still have:

$message = Swift_Message::newInstance("Email Template Test")
    ->setBoundary($boundary)
    ->setFrom(array('[e-mail]' => 'Mailer Service'))
    ->setTo(array("[e-mail]","[e-mail]"))
    ->setBody($plaintext)
    ->addPart($htmlmail,"text/html");

$headers = $message->getHeaders();
$headers->addTextHeader('Content-Transfer-Encoding','base64');

$contenttype = $message->getHeaders()->get('Content-Type');
$contenttype->setValue('multipart/alternative');

As far as I can see from the documentation (which I don't find too clear), the heading Content-Transfer-Encodingis a text heading, so I should be able to set it as above. Before that, I started displaying all current headers, but was Content-Transfer-Encodingnot listed there, so I had to install it. Therefore, in the above code, I tried to install it.

version 5.4 . Swift_Message .

$message = \Swift_Message::newInstance("Email Template Test");
$message->setEncoder(\Swift_Encoding::getBase64Encoding());
//...

, ( 4 5) addPart. MimePart . MimePart .

$part = \Swift_MimePart::newInstance();
$part->setEncoder($message->getEncoder());
$part->setBody($htmlmail, 'text/html');
$message->attach($part);

Content-Type: multipart/alternative; boundary=****, border charset Content-Transfer-Encoding: base64.

:

var_dump($message->toString());
