That is rather extreme. I found that matching because really good after 1000
messages.

I think 1000 mails is plenty, unless you are obsessed with never getting a
false positive. LWN.net did a study on this and came to a similar conclusion
(sorry, i don't have the url handy.)

I used to discount this, but I am starting to agree that sharing is bad sin=
ce
I am now getting degraded matching quality (spams getting through when they
should not) with a shared database.
