I think you must not understand what I'm asking.

You showed:


     Content-Type: application/pdf;

This is only the terminating boundary from a prior multipart part and
the beginning of the application/pdf part.

The complete message may have headers and boundaries like

MIME-Version: 1.0
Content-Type: multipart/mixed;

Content-Type: multipart/alternative;

Content-Type: text/plain
[plain text body]

Content-Type: text/html
[html body]


Content-Type: application/pdf
[pdf attachmemt]


That's what I want to see. The above is a properly formed MIME message
with structure


I want to see the equivalent headers and boundaries from your message.
Then we will see if the fault is that the message is defective or
there is a MailScanner issue.
