Well, surely the test of "to scan, or not to scan" should be
per-message, not per-call? Unless I've misunderstood the intention,
I'd use an $acl_mN variable, rather than an $acl_cN.

Per-call tests are good for revealing dictionary scans, on the other
hand. But the kind of aggressive dictionary scan which was common
some time back seems to have got quite rare now. Accessibility of
countless virus-infested zombies makes it -so- much easier for them to
do their dictionary scanning in a stealthy fashion.

The ACL stanzas which I once devised for it are rarely triggered
nowadays, and they do run a certain risk of false positives (for
example, when somebody has the bright idea of starting a new mailing
list and seeding it with old addresses!).
