Thanks. Evolution seemed to choke on opening the mail with viewing
Message Source, so I had to seek it out and open with gedit. Here's what
I found:

--Apple-Mail=_54DF1950-4BCD-4426-9730-DEB7448E058D
Content-Disposition: attachment;
filename=CurrentSpiritualCareGrandRoundsUnderwoodClevClinNov2013.pptx
Content-Type:
application/vnd.openxmlformats-officedocument.presentationml.presentation; x-unix-mode=0644; 
x-mac-type=50505458; x-mac-hide-extension=yes; x-mac-creator=50505433; name="CurrentSpiritualCare[...].pptx"
Content-Transfer-Encoding: base64

It then has 176000 lines like:

The strange thing is that when she sends the email w/the pptx attachment
to my Windows box it opens fine in Thunderbird there. Everything on line
seems to focus on Windows mail (Outlook) creating the problems for Mac
Mail to receive. Here it seems to be Mac Mail creating the problem?

Thanks.
