Possibly, but it will be a bit of a development job and require that you
learn your way around the facilities available in Exim configurations.
The documentation is at
http://exim.org/exim-html-current/doc/html/spec_html/
I suggest you possibly want to start with the idea of
at transport which
a) deals only with one recipient at a time
b) removes all To:/Cc:/Bcc: headers
(actually there should never be any Bcc: - but best to be
safe)
c) Inserts a fresh To: header built from the (envelope)
recipient name.
Be aware that this level of manipulation will break most
digital signing of the message (such as DKIM).
