Re: attachments become unreadable and mail turns to winmail.dat

The clients on which this happens (winmail.dat) are outlook 2000 and outlook
Xp and outlook 2k3.

the format of the mails is indeed rtf.
however the attachment problem occurs on both rtf and html mails.

and this bugs me more than the winmail.dat because there i know a solution.
If I change the format at server level to plain text for a certain domain the
problem disappears.

The attachment problem is however a bit more curious and no standard
solutions are working.

david
