How do I bounce back all mails over 50 recipients

[Alex Neuman van der Hans]

So all a spammer would have to do is send his/her spam to 50 people on your server and spoof the "from" address... Your server would receive it, refuse to deliver it and bounce it to the spoofed address, thus enabling the spammer to send email through your server. 

I don't think that's what you want.

It will deal with local users sending out to more than 80 people, but not foreign users sending to more than 80 total but less than 80 on his server, or foreign users who sent to his server using bcc to less than 50 people. If the sender splits recipients it will not trigger either.

If the sender is going to split it . then forget thats ok.
I think it should be trivial to bounce back from inside Mailscanner on
rcpt count. Just that how do I generate an NDR  and send the mail back
