I know it's a permanent error. Here's the situation. I do front end spam
filtering. What happens sometimes is Iset up a new customer and they
point their MX to me and I clean the spam and forward on to them. It
works for an hour and then their server realizes it's not the lowest MX
anymore and starts bouncing everything I forward. I don't know about
this unless something alerts me like the customer calling about reports
of email bouncing.

What I would like to do is on certian hosts treat a 550 error as if it
were a 4xx error so that I stored the email till they fixed the server.
