The general case here is that you are running into an error returned
*within* the acl clause (even if the DNS lookup fail was cached earlier).
To avoid that, pre-build a string into an acl_<variable> in earlier
'warn' verb clause(s) where any error(s) returned affecteth not your
ultimate error message.
You can progressively concatenate as you go into a single (or few) such
variables.
Then concatenate that (such as it is) with any other text as need be
within the ultimate deny/defer/ acl clause.
e.g.
warn
set acl_c1 = $sender_host_address $sender_host_name
warn
set acl_c1 = Traffic from $acl_c1 for [EMAIL PROTECTED]
Later:
deny
message = Rules were broken for $acl_c1
Where a failed lookup in or before the 'warn' may leave nothing more in
the acl_c(x) than the connecting IP address alone, but we do not care,
and those tests are not called again in the 'deny' that returns the
message we built.
(fragments shown not specifically tested, but we do similar stuff all
day, every day).
