  The practice of having positive scores in spamassassin for SPF
records should be strongly discouraged.

Wether MARID encourage or discourages it will make no
difference. Scores of the various tests in SpamAssassin are not
determined by an human trying to guess wether "sex" should be more an
indication of spam than "viagra", or less. Scores are determined by
using the actual tests against a corpus of spam and a corpus of
ham. See http://wiki.apache.org/spamassassin/HowScoresAreAssigned.

So, scores do not depend (too much) on human opinion or
prejudice. Wether SPF "pass" is a good spam marker or not will be
determined automatically.

Do note that, at the present time, the scores of all SPF-related tests
are very low (probably reflecting the small number of SPF-enabled
domains). See http://spamassassin.apache.org/tests.html and search for
SPF.
