Users of LuxSci’s Premium Email Filtering service now have a new and very powerful weapon to stop this kind of spam — “SPF-enabled allow list entries”.
This feature allows you to easily receive protection from forged spam messages while at the same time ensuring that legitimate messages sent between users in your organization are not filtered or caught as spam.
