Not accepting slashes would seem to put that MTA in violation of RFC

It isn't a violation of the protocol, it's a local policy issue.

on the grounds that anyone using such an address is liable to be playing
silly buggers with pipe or file transports. The details of this policy
have varied slightly from release to release.
