Quite. In order to achieve some clarity, please let me say:
A triggered 'accept' is not 'permanent' until end of DATA. Period.
This assertion is wrong.
An "accept" verb in an ACL simply means that the ACL in question has
accepted *whatever it is processing* at that time.
An "accept" in any other ACL than the final one in the flow simply
passes control to the NEXT ACL.
In the case of DATA (which is usually the final one), it is a permanent
acceptance of a message. In *any other ACL*, control passes to the next
ACL.
A triggered 'deny' class verb is 'permanent' AT ONCE. WHEREVER it is.
Indeed. For whichever part of the ACL flow you're in, a "deny" is
immediate.
Please don't muddy the waters.

Given that - absent a link fail, time-out, or other earlier bail-out -
(which by definition cannot be an 'accept') DATA is ALWAYS the 'final
one' in the phases of an smtp session - whether you have any
customization to the default handling or not...
How can you say that the statement that:
>> A triggered 'accept' is not 'permanent' until end of DATA. Period.
...is 'wrong'..
.. and THEN go on to say the same thing!

Is stipulated. Understood. Inherent. Nature of the beast.
Near-as-dammit unavoidable, even.
Ergo inserting it is irrelevant. Red Herring.
THAT is 'muddying the waters'.
Surely you did not interpret any part of this to have implied that an
earlier-phase 'accept' was somehow infectious, parasitical, viral, or
....wot? child-bearing? ... immortal, even?
