Another feature - something I've asked for before - is the ability to treat a 5xx error as a 4xx error. I know people have complained it is dangerous but you can put all kinds of warnings in the docs about it. Here's why.
I'm doing front end spam filtering. People point their MX to me and I clean it and forward the good email on to them. Normally this is simple. But sometimes what happens is that when the recipient's server is no longer the lowest MX it forgets it is hosting the domain and starts rejecting 550 all the email I'm forwarding with a "relay denied" message and it creates a bounce. I need to intercept that so that I can do something else on 550 errors other than bouncing. -- ## List details at http://lists.exim.org/mailman/listinfo/exim-users ## Exim details at http://www.exim.org/ ## Please use the Wiki with this list - http://wiki.exim.org/
