cannot see attachment

I just sent a past M.exe to myself using Mahogany on one 
machine, and when I look at it (no matter which viewer) in
my IMAP account I cannot see the attachment.  If I look at
the raw message (ctrl-z), I can tell the attachment is 
there.  It has MIME header
        
    Content-Type: APPLICATION/X-MSDOWNLOAD; NAME=M.exe
    Content-Transfer-Encoding: BASE64
    Content-Disposition: ATTACHMENT; FILENAME=M.exe


If I look at the MIME sturcture (shift-ctrl-z),
it says it is Mulipart-Mixed by shows only the plain text 
part (of 0 bytes).

Cheers,
Alan Isaac
