Viewing winmail.dat attachments on Mac

Usually while using the Apple Mail, I do get hit by the winmail.dat attachment. This is a problem to do with Outlook 2003 rather than the recipient program. The description of the problem as well as one possible solution is given at the Microsoft support site, which is for the sender to set the mail format as Plain Text.

The other option is to use the TNEF's Enough to read the contents of the winmail.dat

Starting from there, I was wondering whether there is a way to automate this using some Automator Script or the QuickSilver application. If anybody has a solution on these lines do ping me.
