I see where you are going with 'domainlist', but find it simpler to put the
complexity into the DB and write shorter SQL calls...
i.e. an SQL '.....where $acl_m10' (full stop) tests it for null/not null,
avoiding need for an 'if def:' in Exim / pcre, AND ALSO eliminate the need for
double-handling acl_M10 in the first instance.
OTOH, our DB, authentication setup and routers are such that we don't need that
clause at all. 'helo_data', for example, can be a field in the same db record
as
each user.

I expect 'message' to survive, but don't mind that it is no longer intended to
apply to a 'warn'.
Technically, a 'warn' has no part in communicating directly with a client -
only with variables, logs, headers, etc. 'inernals' if you will.
As I think of 'deny', 'drop', 'discard' as 'reject-class verbs', I think of
'warn' as an 'accountant class' verb. IOW, a scorekeeper or umpire, not a
player.
YMMV,
