Why use PGP between mail servers? SSL/TLS can be used for that, too.
Actually, opportunistic server-to-server TLS is supported by many mail
server software, and is becoming more and common.

Using PGP for anything less than end-to-end encryption seems pointless
to me. Particularly if it distracts mail server administrators from
enabling server-to-server TLS, which we need anyway to protect the
metadata (headers) that are *not* encrypted by PGP.
