Just exactly *HOW* do you measure ``literally 100%''?

How do you account for false positives and false negatives?

Do you manually examine every message, whether or not flagged as spam?

Personally, I receive between 2,000 and 3,500 messages each day, of
which ~200 are flagged as spam via procmail rules and spamassassin.  I
receive email from a very heterogeneous mix of sources, including
mailing lists, companies whose products are interesting, personal
contacts, technical resources, &c.  For me, one or two messages each day
improperly flagged is the cost of doing business on the Internet.

As impressive as that phrase ``literally 100%'' is, I am considerably
skeptical.  I have never -- in thirty years -- found any software
utility that can beat five-nines statistics.

How can we get hold of yours?
