sympl-mail: Enhancement - Add a whitelist for Exim
If you're potentially blocking more mail due to the enhancement in issue #282, the ability to whitelist hosts/IPs, would be useful to skip all spam filtering and consider the source as trusted.
This would likely need to be configured on a whole-host basis, and maybe should be located in /etc/sympl rather than the Exim config directory.
Maybe something which can be done automatically based on a previous good reputation, similar to the blacklists used by the firewall?
