I do have sender now that is being blocked by RBL even though I have whitelisted it in "Configuration -> Mail Proxy -> Whitelist". As I've read the docs for this option: All SMTP checks are disabled for those entries (e. g. Greylisting, SPF, RBL, …).
But still I am not able to make exception for this sender to get it pass this RBL block. Am I doing anything wrong?
