Use whatever test you need within a warn verb acl clause to set
'whatever' into an acl_m variable within an appropriate phase of the
smtp session. You may even begin in CONNECT phase with an acl_c - which
do not survive to reach routers, by copying its value to an acl_m, which
do persist.
Acl's can use more complex logic with fewer restrictions than
router/transports.
Routers can read acl_m variables and behave accordingly.
