One other question. Some spam systems have a feature where if a user receives spam in their email, they can simply forward that email to a particular email address to add it to the black list. Is that option available?
In reality, few of the real spams that get through the UTM's anti-spam come from an address worth blacklisting. Those that come through repeatedly are usually mailing lists that the end-user opted into at some time - the answer is to opt out both from the particular emailer and their list provider at the bottom of the spam.
