Bizarre: GPRS Cingular Mailinglists and Eudora

[Mike D.]

This one has me stumped.  While checking email via a pop server, if 
I'm connected via GPRS/ bluetooth on Cingular, my email mailing lists 
(that I'm subscribed to in Digest mode) come through as a ".cab" file.

Anyone seen this?

(since I can't read your responses, please CC: me directly)

The file starts like this:
MSCF    -      ,       

 
      Z   
 
 õU              bluetooth-mac 
Digest #250.txt


Is Cingular using some weird email proxy that is fsking my emails? 
(as Sprint does with Images ?)
