I can't speak for Mr. Boyce, but _I_ was talking about _end_ _to_ _end_ 
encryption, i.e., encrypting data at the originating MUA,  in such a way 
that only the intended recipient(s) are able to decrypt it, usually 
using the built-in functionality of their MUA. Some systems use X.509 
certificate-based cryptography, and some use GPG/PGP. Neither of those 
methods depends on the MTA(s) or servers in between the MUA(s) involved.
