Email attachments not saved to document library

Question

Another system generates a report and emails it to a sharepoint document library - the email has a PDF report attached - but the pdf file is not extracted and saved to the document library.  We are saving the original incoming email in the library,
and if I download that .eml file to my PC and open with outlook, I can see the PDF attachment there, and can open it, etc.
If I forward that email message (that I retrieved from the SP document library) using outlook back to the same document library email address, the PDF attachment will
be extracted.  Passing through outlook seems to alter it and make it extractable.
The person on the sending system says they don't have any mail/encoding options that they can tweak - any suggestions as to what the cause of this might be?

Answer 1

Message header is below.  The report is generated by SQL Server Reporting services - via another sharepoint site that another group manages (somehow it is integrated with that other sharepoint site)
