I receive unreadable attachments from Outlook users regularily. Actually, attachment
(say, .DOC) is hidden inside of attached "winmail.dat" binary file. And seems, Outlook
owners do not control this behavior properly: one message have normal MIME data, one have
winmail.dat instead, and sender knows no difference in his/her actions.

This is not related to Postfix. And surely, we do not use Outlook.

If necessary, winmail.dat can be read with a help of good binary editor. Just cut it's
head, and get your data - if the data file has clear start signature. GIF, etc.
