I want to filter incoming mail so that we only accept mail for people listed in the Active Directory. We get a lot of spam to random names at our domain.com. I would like to stop this. I turned on recipient filtering in Global \ Message Dilivery \ Recipient Filtering. I think there must something more to it though, because that doesn't seem to work. When I look up help on this, it says that enabling recipient filtering may be a security risk.
Anyone have thoughts on this?
