Chuck feels very strongly about requiring SPF being done

In theory that's correct, like Julian's new PermError concept.
such as SpamAssassin and other filters are doing.
I'm interested in opinions from others.
But in practice I trust that SA gets it as right as possible,
and AFAIK it can be also used during SMTP. And SPF stands and
falls with the "support" of spammers, without SA checking SPF
the spammers have no convincing reason to "support" SPF. Bye.
