Where I am wrong about what? I don't think I said anything to the
contrary. You're not reading what I'm saying.

Thanks - the eggsucking will go much better now. From your loving Grandma.

And my point remains that the avoiding of SA where that means not
letting it see the ham will stop the Bayesian bit working. If that's
not a problem for you, then fine - but don't tell me I'm wrong about
SA when what you mean is that you don't see this downside as a problem
in your circumstances.

No one has done this? I think you mean that *you* haven't. Please try
and resist the temptation to speak for everyine else.

The problem, as always, is definining 'reputation'. Should be easy
enough (as I suggested before) to update a database with
greylisting-style data after a message passes SA, and check this db in
an early acl for the next message, but is this enough of an indication
of reputation to risk bypassing the very thing you've implemented for
the purpose of scoring a message in real time? (I'm not saying it
isn't, I'd want to see stats though)
I guess it's all in the timing - you need the whitelist window to be
long enough to continue letting in the good stuff, with a re-scan
every now and then to keep the db entry fresh, but not so long as to
let in spam which disguises itself with the same fingerprint, which is
not uncommon given the habits of zombies.
