# SPF support:
#   "pass" is nice
#   "neutral" is somewhat bad
#   "fail" is bad
#   "softfail" is bad, but not as bad as "fail"
# These are more trustworthy results than the SPF_HELO rules.

# NOTE: SPF_HELO_PASS is not incredibly hard to fake, so shouldn't
# provide much in the way of points compared to SPF_PASS et al.
# However, a *failure* is still a very good spamsign.
