# SPF support:
#   "pass" is nice
#   "neutral" is somewhat bad
#   "fail" is bad
#   "softfail" is bad, but not as bad as "fail"
#   "permerror" is very bad, and means the domain doesn't have a valid spf record
# These are more trustworthy results than the SPF_HELO rules.

# some are "userconf" so that scores are set by hand?
