Yes - you may use a 'warn' verb to carry the test and variable if it doesn't fit
an existing acl clause.
FWIW, you may wish to handle 'hostmaster' and 'abuse' the same way as
'postmaster' (optionally 'webmaster' as well), *and* allow domain_literals
(postmaster@<IP>) on (only) those addresses.
This because your <domain>.<tld> registrar or upstream ISP might need to reach
you 'regardless'. Think DNS failure or service suspension.
The acl variable would probably be 'lighter weight' than SA as far as resource
load, and arguably more focused for the specific purpose w/r keeping track of
what you are doing.
