I would say that Exim is doing the right thing; and that it is
normally the responsability of the MUA. Any site that wants to
support broken MUAs can easily use headers_remove to delete the
Bcc: header. It is only slightly more work to restrict Bcc:
modification to locally submitted messages.

And if the offending MUAs generate X-Mailer: or similar headers;
it should be possible to restrict Bcc: 'fixing' to cases where
there is a likelyhood that it is actually broken. And it should
all be doable with existing Exim functionality.

Perhaps someone with some time on their hands could come up with
a good example of how to do that...
