	Mine mails the lowest 100 scoring spams (I use the defaults of tag at
5, quarantine at 10.. And the end user can adjust that how they see fit)
in the quarantine daily, and the subscribers appreciate looking that
over rather then not having a usable Inbox. (I do domain hosting)

	As it will get lost in an Inbox full of spam.. Spamassassin quarantines
2500-3000 spams a week on one of my accounts, I'd lose lots of legit
email if that was in my Inbox... That said, I don't remember digging one
out of the quarantine in a very long time, I do get some forwarded jokes
tagged because it's been forwarded 10 times or something.. I can live
with that..

	In my case it's a usable Inbox vs 2500-3000 spams a week clogging it
up.. Spamassassin isn't a fire and forget piece of software.. You need
to train bayes, keep rules updated, write rules, etc... I hear
bogofilter is decent as well, might look into it.. But there's no way I
could handle using email without filtering to a quarantine..
