One of my customers (using Outlook via Exchange) keeps sending me winmail.dat attachments. I know from experience that this means somewhere the message is being sent as "Rich Text" rather than "HTML".
However he's checked and Outlook is set to use HTML.
Any suggestions? I don't have Outlook installed (I don't think they have a Linux version yet :-), although I think it's possibly at an Exchange level anyway, and I know some people her administer both. It seems to be only affecting me - they haven't explicitly said this but I get the impression they can send attachments to (eg) Hotmail and Gmail which (as far as I know) don't support Rich Text either, so it may be something somewhere as got configured against my email address. But I'm just speculating!
Something else they haven't said, but I can hear them thinking it, is "why don't you just use Outlook like everyone else", so I'd like to show this is a config problem their end not just me being "non-standard".
Grrrrr....

PS: I do have tnef installed so I can extract winmail.dat files but when all they're sending me is screenshots it's a pain not to be able to read them inline in Thunderbird.
