multipart/alternative vs. multipart/mixed

[smashing]

I'm attaching a PDF document when sending an email message. The first part is plain text (Content-type: text/plain) second part is html and the 3rd part is the attachement. Now if I use multipart/alternative only the HTML is recieved, so I try using multipart/mixed but what happens now is that everything is recieved even the plain text. How is this situation corrected?

You could try PHPMailer class that people in this forum usually suggest.
