--- Comment #2 from Bill Cole <[email protected]> ---
The rule is perhaps misnamed, but it is operating *as intended.*=20

77.220.60.126 has a PTR to mail.tpp.ru, but mail.tpp.ru only has an A record
saying that it is 79.135.227.253.=20

rDNS that isn't confirmed by a forward record is entirely untrustworthy and=
 is
a strong sign of spam.

--=20
