I'm get a spate of false-positive spam filtering cases based on: 3.5 XPRIO Has X-Priority header
I'd like to turn off "XPRIO", but I can't quite figure out where it's set. It's not in /etc/spamassassin/local.cf (though maybe I can override it there).
FWIW, 3.5 seems way too high for a spamassassin rule for this -- lots of messages sent X-Priority headers, usually with value 3 (normal). I can't tell if this is a new setting that came with an upgrade, or if I just started receiving more emails with the header.
