A method I use that has not 'messed up' in several years:

New subscribers are on review. I filter my incoming
listowner e-mail for this string in the BODY:

 Notification-To:

This e-mail filter puts the offending message into a
different queue. I write back asking them to turn off their
"return receipt" notification, and to re-submit their
message.

I also offer to receive a test message and confirm that
the thing is actually turned off.

By the way, I do not agree that this is a solely Microsoft
issue. I believe that other e-mail programs have also
implemented this "feature." My memory suggests that
some versions of Pegasus, for one instance, may be able
to produce these.

 Pax,
