Thank you for your post.
In MagicSpam PRO there is a 'FLAG' option that will enable messages to be marked as spam, and passed to users spam folder for further analysis and exclusion if needed.
However, users also have option to reject those messages on their end, by adjusting their own spam settings.
This means that in order for the messages to be accepted to a user's mailbox, the policy has to be enabled as 'FLAG' or 'OFF' on global level as well as in users spam filters by the user himself.
Hope this answers your question.
