Well, I was using the term to refer to accepting a message which would
otherwise be rejected - I guess that is somewhat different. My objection to
the practice is twofold: (1) it encourages people to misconfigure their
servers (1) it negates the point of maintaining the rfc-ignorant list -
which is surely there to discourage people from being non-compliant.
