No there isn't. One of the problems is what to do about it. You can't
detect it till during the DATA phase of the SMTP transaction. All you
can then do is send an error reply at the end of the message. I know
from experience that many MTAs out there treat any failure following the
data as a soft error, and they just keep trying again...

How does PP reject such messages?
