When I submit/reply to tickets via email with PDF attachments, those attachments do not appear in the UI with the articles.

However, If I go to "Plain Format" I see them in the MIME content of the article and if I "Download this email" they are there as well.

I have installed the PDF::API2 module and don't see any log errors.

I have tried the following combinations, each with the same results. Is there another sysconfig option I need to set? Other attachments do appear.

Content-ID: <AD Group Membership Report.pdf>

Content-Disposition: attachment;

 filename="AD Group Membership Report.pdf"

Content-Type: application/pdf;

 name="AD Group Membership Report.pdf"

Content-Transfer-Encoding: base64

Content-Type: application/pdf;

The system is:

- OTRS 3.0.3
- IIS 7.0 with PerlEx.
- Exchange and hMailServer are relaying the messages.
