total cbv bad ptr : 2212 9.09%
total cbv bad no mx : 521 2.14%
total cbv bad no mx host : 0 0.00
total cbv bad connect : 5207 21.39%
Approximately 22% failed at the PTR, MX, Connect level.
That should be 33%. I just want to correct this because it is significant.
Most systems do provide an MX. They must put a server behind it, but they
do comply with "DNS" - so DNS based proposal need to realized that just
because they have a "record" in DNS, does not necessary mean its valid.
