I undeerstand your wishes, and I feel your pain. However, asking exim
to do this will violate so many normative standards of mail handling I
am just not sure it's a good idea. A 5xx is a permanent reject and
should be considred so - I know that at the larger sites I admin, when I
see a mail I have just 5xx'ed retried, I assume it is spam, and try to
come up with a rule that will catch it as well. I am sorry, but the
wish to work around a permanent failure just seems like a bad idea. It
is just so fundamental to the basic concepts of SMTP handling that I
can't imagine the good outweighing the bad.
