This is almost certainly a client issue - my guess would be the sending 
software is munging the MIME structure of the message (Eudora is 
notorious for this). The best way to isolate the culprit is to cat the 
raw message in the server's spool directory - look for the MIME 
Content-Type header at the top of the message, e.g.

  Content-Type: multipart/mixed; boundary="--rhubarbrhubarbrhubarb--"

then check the individual parts, each of which should start with the 
above boundary string followed by its own header info:

  Content-Type: text/html
  Content-Disposition: attachment; filename="attached.html"

You'll need to consult the MIME spec (RFC2045) if you want all the gory
details, but even a cursory look at the raw message should give you an
idea of what's coming through.
