But you're better-off never accepting the message. Consider doing
cutthrough-routing for these; this means that if the site you are
forwarding to (Google) refuses the message even as late as after-data
(which, given they need to analyse the body, is likely) then so do you
(for the originator talking to you).

This is where sender-verify callouts are useful, despite some people
regarding them as bad. But if you're doing cutthrough you don't even
need that.

The trick is to never accept these messages, so that no bounce is
generated.
