The Exim Specification
40.19 ACL modifiers
Read the stuff on the "message" modifier.

Note that you'll need to make Exim also shut down the connection if you
do this, since that's what 421 means -- the service isn't available and
the MTA has to close the connection.

However, the use of changing the response code still requires you to
keep the same initial digit, so you can't return 421 from a "drop" ACL
verb. If you want this restriction changed then you'll need to present
a convincing argument for it, including rationale, caveats and suggested
limitations to set the new limit to keep people from shooting themselves
in the foot.
