DONE Configurable Action for SPF Neutral
For specific, user-defined domains, allow blacklisting the email even if the SPF evaluation ends with SPF Neutral result. This would make the SPF test actually usable for some
major domains that have not been progressed to SPF SoftFail or Fail yet.
DONE Add the SPF Test to the Whitelist Test Exceptions
Extend the current list of the Whitelist Test Exceptions with the ability to exclude the SPF Test from the whitelist tests. This would allow checking for forgery even if the sender is whitelisted, e.g. by the Auto Sender Whitelist.
