I was thinking of an error message "fix your mailer" instead of simply
discarding, for all offenses. But I have no objection to allowing
non-> quote characters if others want to. My procmail rules were
simply intended as a base proposal to work from, not any final demand.

My proposal errs on the side of avoiding false positives, i.e.
messages that break the rules could potentially get through if the
mailer base64-encodes the subject. However, as far as I know, the
regular offending mailers do not base64-encode subjects.
