well, same thing hapened with some blacklists in the past, which
resulted to high number of FP's.
While FNs mean (much/all) mail not to be detected, FP's are uch worse.
I wonder why SA disables DNWSL rules, with this logic blacklists, not
whitelists, should be disabled...
The logic is that we do not publish rules that knowingly produce errant
scores. Whether those scores are positive or negative has little impact
on that policy.
DNSWL is working to reduce/eliminate that issue which I am very happy about.
