there isn't a concise list of the inputs and outputs.
I'm a bit confused too.
Let me try to stepify what you are saying:
Step 1: obtain domain name from HELO/EHLO
Step 2: DNS query
input: domain name
output: "MARID level" (this is a policy acceptance level), list of
reputation services, some flags
Step 3: DNS query
input: rDNS of SMTP source in _HELO.domain tree
output: "MARID level"
Step 4: query reputation service(s)
Step 5: If match, report "good"
Step 6: obtain domain name from email address of MAIL FROM
Step 7: DNS query
input: domain name
output: "MARID level" (this is a policy acceptance level), list of
reputation services, some flags
Step 8: DNS query
input: rDNS of ?????? in _MAILFROM.domain tree
output: "MARID level"
Step 9: query reputation service(s)
So, what is the "MARID level" in step 2 used for?
And where does the IP address for Step 8 come from?
