We receive a lots of smaps, used the blacklisting feature, by enabling a half dozen bl databases, but we still receive quite a good nbr. Most of these spam (if not all) have the "Received" field as coming from [127.0.01] which is usually local_host. 2 Questions:
1- is this likely the reason why this spams are not rejected?
2- either way how to deal with this.
As of now I don't have the PTR "on", fearing that authentic (but not properly configured) mail servers could be rejected.
