Is there any header that even remotely looks like it's asking for a
delivery receipt? If you haven't done so, try looking at the message
in the archives/private/listname.mbox/listname.mbox file just in case
there was such a header that got removed on it's way to some but not
all recipients.

I haven't seen it on my production lists, and I'm sure some of my users
must be using Outlook.
>Is MS hiding "return-receipt" inside another field, like X-MS-TNEF-Correlator:
That seems unlikely. Perhaps Outlook is sending unrequested receipts,
but that seems unlikely too. Perhaps there is something in the
application/ms-tnef (Winmail.dat) part itself that asks for a receipt.
You could try using content filtering to remove these if you aren't
already.
If you do find a header that's causing this, please let us know as we
definitely want to add it to the list of headers we remove in
Cleanse.py.
