[Macpartners] Re: MIME Types with Eudora and OS X

[Christopher Naylor]

Just to let you all know, I solved the problem!  Yay!

The Eudora 6 manual was indeed correct in its instructions to edit the 
resource fork of the Eudora application.  I found a freeware OS X 
compatible resource editor, Rezilla (available at Sourceforge.net).  The 
EuOM resource, which governs MIME mappings for outgoing messages, contained 
an mapping for Adobe Illustrator, which uses the ".ai" suffix.  The 
mapping, however, was just to match the file creator only, not creator and 
file type.  Since Illustrator and Acrobat are both Adobe products, they 
have the same file creator.  The mapping for PDF was on file type only, not 
file type and creator.  Either because the Illustrator mapping came before 
the PDF mapping in the resource list, or Eudora's preference is for file 
creator over type, Eudora mapped PDFs to Illustrator when 
sending.   Deleting the Illustrator mapping fixed the problem.

I know, I know, I should have tried editing the resource first, before 
crying out for help.  I just thought that with OS X, resource forks were a 
thing of the past.  I have learned my lesson.

Thanks to all who replied!  You guys rock.
