Not in SA.. SA only receives the message. It does not receive the envelope. SA will try hard to guess from the headers (to:, bcc, cc, as well as the "for" clause of Received: headers), but if the information isn't there, SA can't possibly know. However, the tool that calls SA generally does have access to that information, and can bypass calling SA entirely for those cases. One thing to be wary of is if you're integrating at the MTA layer, there may be one message with multiple different recipients. If one is whitelisted but not the others, your tool will have to jump a few hoops to split the message into two copies to scan one and not the other.
