How do I set email attachment reading by extension?

[Walter Dnes]

  I use epdfview to read pdf docs.  Earlier this year, Teksavvy's email
senser switched from "application/pdf" to "application/octet-stream".
Here's how the old and new formats look at the bottom of mutt...

[-- Attachment #2: ARRCPT.pdf --]
[-- Type: application/pdf, Encoding: base64, Size: 47K --]

[-- application/pdf is unsupported (use 'v' to view this part) --]



[-- Attachment #2: TekSavvy_Invoice_CIDXXXXX_20120725.pdf --]
[-- Type: application/octet-stream, Encoding: base64, Size: 104K --]

[-- application/octet-stream is unsupported (use 'v' to view this part) --]


  Trying to read the application/pdf launches epdfview, and can read the
invoice.  The newer application/octet-stream version fails.  I merely
comes out as binary gobbledygook.  What can I set on my system to force
reading by extension, rather than "application/whatever"?
