it seems pretty absurd because the whole point of exchanging mail is to
use well-known services.

for data exchange between two systems and keep it private, it should be
done via an encrypted tunnel (VPN) or at least through an ssl tunnel.

as for sendmail doing what you want to do, there are endless amounts of
documentation for sendmail configuration but it seems that the flaw is a
conceptual, not a practical problem.
