We have a database of "trusted" domains (trusted by us) that publish SPF.
If the sending IP matches the SPF record, it bypasses greylisting (saving
resources both us and the sending host). That doesn't get hosting services
which publish SPF but don't do SRS by greylisting, but it does help
some...we have other means of whitelisting.
We don't reject anything for SPF failures.
The above work is done by a socket call to a daemon, so I can't present an
ACL for it.
