The IPS will not know if relaying is allowed. Only the SMTP server can
send this response. So, you can't "take off this task" from the SMTP
If you are trying to deny this response from leaving your SMTP server and
going back to the client, you can do that with an IPS, but it's better to
make that configuration change on the SMTP server instead of dropping the
packets in midstream.
