Ah - forgot to mention one of the BASIC conventions:
Any 'deny class' verb is permanent. Session having been terminated, no
later 'accept' could possibly act.
An 'accept' OTOH is *temporary* ..
...unless it is the LAST one to act in acl_smtp_data.
'endpass' after an 'accept' can skip all remaining clauses in a given
phase. But any LATER phase can still execute a 'deny'.
In essence, 'accept' just means 'continue the march'.
