Ok, that makes sense; it sounds like mailing list managers, when
receiving, should always impose a directOnly attribute on lookups; is
that right? so the tested address is the "From:" no matter what other
"Sender", "Resent-*", etc headers are present.

IF you are a mailing list accepting submissions, ignore the
usual algorithm and test only the 2822 "From:" header.
IF the MUA is capable of displaying "From X on behalf of Y", apply the
Caller-ID algorithm to extract the appropriate responsible sender.
IF the MUA is not capable of displaying "From X on behalf of Y", test
only the "From" header.
