If the attachment is called "winmail.dat" then this is a proprietry Microsoft Outlook format for attachments (application/ms-tnef). It doesn't follow any standard. Bill Gates only knows why they didn't just use the standard MIME format for multipart attachments. You can decode these attachments under Unix using the program 'tnef'. But Sqwebmail would have to jump through hoops to decode them. Outlook reads them fine of course, since it's a Microsoft file format. If anyone has an FAQ on how to configure Outlook and/or Outlook Express to send MIME attachments instead of TNEF attachments, I'd be very interested to see it (so I can just mail it to anyone who dares send me a TNEF attachment in future) Regards, Brian.
