Add option to 'soft fail' on Reverse Lookup (PTR) failure
At present the options for action on PTR lookup failure are to close the connection - a hard fail.
As others have observed this causes a lot of unhappy customers because emails from legitimate senders fail to be received, yet it also stops a lot of spam emails so it is a desirable test to have turned on (in my opinion).
Please consider the option for a soft fail on PTR lookup failure.
For example I would prefer the option to increment the spam score against emails that fail rather than closing the connection outright.
Thank you for sharing your idea with us to add a soft failure option for PTR lookups. It will be considered for future versions.
