# 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.

# provide much in the way of points compared to SPF_PASS et al.
# However, a *failure* is still a very good spamsign.
