Question - Attachement from Outlook ("winmail.dat")

Hi all,

I have a slight problem when receiving e-mails. The attachments along with the body of the message are appeared as one attachment with the name "winmail.dat". The point is that I get this format only from one person and actually when he forwards the e-mail. He uses Outlook and this is a stupid parameter of Outlook whether to include the original e-mail as is or as one attachment. By the way I have already asked him to make sure that this parameter is off (that is parameter declares not to include the original message as one attachment) but this also did not work and it is really difficult to mention to everybody not to use this option.

So, I wonder if there is any extension or anything I can do, on my part, to solve this out.

Thanks
