I've just checked the spamicity for the mails I'm getting and they range
from 0.5 to 0.9. I use two-state filtering with default cut-off value
(0.99).

I don't like the idea of lowering the cut-off. With the amount of spam
I'm getting it's impossible to go through the spam box manually and
check for false positives. I do know I get some occasionally even with
this setting because two or three times in the last year I found a mail
I was expecting in the spam box.

By the way, I'm using bogofilter with procmail and constant training (-u
option).

Maybe it's time I switch to three-state filtering? I didn't set this up
in the first place because I didn't saw a particular benefit in this.
You have to read through both inbox and unsure folders anyway, so I
don't see why this is better than just having everything in inbox.

I had pretty much the same experience with those.

Best regards
