[exim] [n@@b question] delete email if 550 error

Hi all,


I'm using Exim as a MX backup server, and it happens to have this kind of
rejection message when SMTP delivering:

host mail.domail.com [67.XX.XXX.X.X]: 550 This message scored 27.3 spam
points.

So instead of a bounce message to the spammer, I would like Exim to
automatically deletes this kind of message (I guess it should be a
condition statement in the config file?).

Any help?
