The general rule (not just with Exim) is to work on the minority case -
IOW the forgery, the 'lie', the just-plain-wrongness.
Providing you hammer the bad-actors along the way, usually all the
'accept' usage you need is one single, naked 'accept' verb as the last
line of each acl_smtp_<phase> case-structure.
No conditionals required on that one.
It is the deny-class verbs that fry the bastards. And the 'warn' verbs
that attach the electrodes.
