Yes, supporting that Microsoft abomination called "winfile.dat" is on my to-do. Thanks.
I've been plagued by this problem recently when emailing attachments to myself from my desktop Outlook 2003.
The general winmail.dat problem that people encounter is usually solved by forcing the email to be sent from Outlook as either Plain Text or HTML, and not "Rich text/RTF".
