Let's not debate the defintion of a quarantine. To me, an IMAP Junk
folder is a quarantine. reviewing my previous post:

- junk folder: This is an IMAP folder that the user sees in his MUA.
- spam headers: the message is seen by the user. it is up to the user to
create rules in his MUA to flter these
- tagged subject: the message is seen by the user. it is up to the user
to create rules in his MUA to flter these
- webmail: the user has access to his webmail and thus to his quarantine
- webmail quarantine: the user has access to his quarantine

so 5 out of 7 of the proposed mechanisms provide direct access by the
recipient. Choose for yourself...

I myself use IMAP folders, and I check my Junk folder periodically. I
use .Junk, .Junk.Trash and .Junk.Error folders. The .Error is for false
positives, the .Trash is for confirmed spam, including False negatives.
server scripts use these for filter training.

As a recipient of a lot of "rejection code", I can only tell you this:
stop it. If you think that fighting spam is as easy as rejecting mail,
then you are wrong. You are free to rject mail if you think it is spam,
but you are responsible of your own errors. As one my teachers used to
say: you can cheat, but don't get caught.
