Doesn't matter. If the router doesn't match and testing moves to the
next router the failure message option for that router is not used.
Some routers might be doing very specific things and it would be nice
to tailor the error message if a router fails & no_more is given.

Agreed. I guess what I had in mind is similar to how the ACLs work
with a : 'deny message = no such luck' at the end. The analogy I
guess is a set of routers at the very end which use :fail: to give a
specific message for whatever condition you like and that's all they
do (message for a virtual domain, cancelled users etc).
Part of my reason for wanting to do this is that the current
'unrouteable address' message is not specific enough (i.e. could mean
an internal network failure?). I was hoping that if I made it
blindingly obvious there's no-one here with that address, the spam
merchants might actually take the address off their lists (one day).
You never know..
Thanks
