[TYPO3] Sending mail with attachments using t3lib_htmlmail

[Rens Admiraal]

Hi all,

I'm trying to send mail with attachments, but I don't get it to work  
right.
Just sending the mail without the $mail->addAttachment line works  
fine. But, when I add the attachment the mail gets corrupted, and  
shows all headerdata in the body of the mail (including the content  
of the attachment). I've added an example beneath the code.

What am I doing wrong?

			$mail = t3lib_div::makeInstance('t3lib_htmlmail');
			$mail->start();
			$mail->useBase64();
			$mail->charset = 'iso-8859-1';
			$mail->plain_text_header = "Content-Type: text/plain;  
charset=iso-8859-1\nContent-Transfer-Encoding: quoted-printable";
			$mail->subject = $subject;
			$mail->from_email = $from_email;
			$mail->from_name = $from_name;
			$mail->organisation = $mail->from_name;
			$mail->replyto_email = $mail->from_email;
			$mail->replyto_name = $mail->from_name;
			$mail->mailer = $mailer;
			
			foreach ($attachments as $file) {
				if (is_file($file)) $mail->addAttachment($file);
			}
			
			$mail->setRecipient($this->form['toaddress']);
			$mail->setPlain($body);
			$mail->setContent();
			$mail->setHeaders();


Example:

This is a multi-part message in MIME format.

------------part_1_469c6fbf3ad1b
Content-Type: text/plain; charset=iso-8859-1
Content-Transfer-Encoding: quoted-printable

Mailbody

------------part_1_469c6fbf3ad1b
Content-Type: application/octet-stream
  name="dummy26.doc"
Content-Transfer-Encoding: base64
Content-Disposition: attachment;
  filename="dummy26.doc"
