Setting it to 127.0.0.1 doesn't make a domain go dead... in fact you
actually end up with no control over it at all since you then can't
deny anything as it never gets to you.
We used the following...
accept domains = *BADDOMAIN.tld
endpass
message = The BADDOMAIN Mail Domain is no longer in service.
log_message = BADDOMAIN IS NOT A VALID DOMAIN - $local_part
local_parts = /etc/exim/users-baddomain
verify = recipient
Basically the only users listed in the local_parts list were
postmaster and abuse... Any other user address was denied.
We ran something like this for about 6 months on a domain that we
took over that had up to that point accepted any and everything
for more than a year. When we started using it again, the spam
had dropped quite a bit. Still heavy but mainly for user accounts
that don't exist now so it just gets denied.
