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

E.g. over the past four months or so, every single spam that has come
through has been caught.

How do you account for false positives and false negatives?

Haven't had any of either in four months.

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

Yes.  I go through my quarantine box daily to detect false positives,
and would know if I received a spam.

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.

I'm not suggesting DSPAM is capable of this for every user - and I am
certain that I will receive some spam eventually to ruin my golden
streak, as there are always new types of spams to learn.  My wife
doesn't get 100%; she's been getting around 99% until I tinkered with
dictionary lately (she's one of my guinnea pigs)..and I've talked to
some users who are only getting around 95%...please don't think I'm
trying to suggest my solution is the end-all-be-all solution.  But as
for me, yes I'm getting 100% so far.

How can we get hold of yours?
