Initially, I was not thinking of a DNS-based whitelist, but more along the lines of a published trusted IP list that could copied into an access file. This would mimic the whitelisting technique used in for the Greylisting pythonfilter.
I have found that there is a DNS whitelist published by Sender Score: http://www.senderscorecertified.org/senderscorecertified/technical.php Furthermore, I was reading the documentation on DNS ACCESS LIST in << couriertcpd(8) >>. It seems that one can initialize environment variables using Access Lists. Specifically, the docs state: /var/[//n.n.n.n/] can be optionally followed by a comma and a text message, which will be used instead of the TXT record. The text message may include a single @ character somewhere in it, which will be replaced by the listed IP address. With this in mind, if one were to specify -block=allow.example.org,BOFHCHECKHELO/127.0.0.10,0 Wouldn't this result in a zero in the that variable, which should then be (theoretically) treated by couriertcpd in a similar manner as having that IP address listed in an access list with BOFHCHECKHELO=0 in front of it. Look forward to feedback on both the viability of this method for whitelisting, and also about experience anyone has with Sender Score Certified.
