I have a Mail client that want to run greylisting but want to bypass Office365 and Google.
I have fond some users that run Postfix that create a custom "postgrey_whitelist_clients.local" file where they add what IP/Domain name they like to whitelist.
So yes I know that it is not supported and that greylisting is not recommended.
But my Client wants it and is really really a fan of it.
Trying to look at the code to see who UT handle Greylisting to see if one can do something.
Did not give much and it looks like UT just stores all current sessions in /usr/share/untangle/conf/greylist.js
Any pointers would be appreciated.
