Potentially.
However you would have to read the message before you could make a
decision (this is a content handling hook), so your error response
would occur at the end of DATA. Some MTAs do not handle negative
responses at this point correctly. Maybe it would be possible to hook
the existing code that rejects this stuff on subsequent sends correctly.
