- another way (possible that will be more easiest, and good enough for advanced configurations) = single variable that may be set in block of exact ip listener configuration , as for provided before example may set variable "auth_db_suffix" = string("dc=domain1,dc=tld") for definition "local mail.domain1.tld" and that variable are inserted in auth block via variable inserting mechanism ...

Again not possible, because config parsing is done much earlier.
