No, they are unrelated, so there is no need for them to match.

They may use this for whitelisiting, not blacklisting. similar to SPF. but they should not consider a mismatch as an anomaly. > + Does the hostname *forward* resolve to the IP I'm being contacted from? I guess you use the term "hostname" for the HELO argument. Some people do this, but: - it will cause FPs - The RFC recommends against it > + Does the IP *reverse* resolve to the hostname? if the hostname is the HELO argument, then no. there were some borked filters that do this, but this is borked... what is done is: - resolve the client IP. get the first returned PTR - resolve this PTR and check that the original IP is returned by this resolution. note that the PTR and the hostname are two different terms (even if they may be set to the same value in many cases). > >> The OP needs to describe the problem more accurately.
