     The Transport Neutral Encapsulation Format (TNEF) messages are 
     probably being sent by someone using Microsoft Exchange because the 
     Email address for the Photo-3D list entry is enabled for MAPI and/or 
     MIME encoding. If MIME is disabled then UUENCODING is forced but you 
     will then receive a WINMAIL.DAT file as an UUENCODED attachment. As 
     far as I know at present it is difficult for a user of say WIN95 using 
     Exchange or Microsoft Mail to disable the sending of this file which  
     contains rich text formatting of your message plus URL links etc. I 
     believe that one possibility is to disable MIME encoding at the 
     senders end (no MIME envelope is generated), and then to ensure that 
     the attached WINMAIL.DAT does not get posted into the PHOTO-3D list. I 
     have researched this subject in general and found that it is an 
     increasing problem for EMail systems that use SMTP transport protocol 
     only. As far as I know there is not as yet a simple solution to this 
     and it has the effect of increasing plain text message sizes and 
     wasting bandwidth - blame Microsoft.
