You mean such an interface would be confusing to some users?  May be true.

On the other hand, moving messages is much more convenient than acting 
on the mail client and the command line at the same time.

But a clever cron solution might also do the job (thanks, Jérôme), even 
though not so well.  For my own usage, I am considering a setup where my 
SPAM filter drops the mail into some folder, I then sort it and put it 
in an Actual-SPAM and Actual-HAM folder, and a cron job cleans the 
Actual-SPAM folder and reprocesses the Actual-HAM folder as if it was 
new mail.

I don't understand.  As long as you are able to move messages with your 
webmail, it would work.

Or are you talking about a configuration where you fetch your mail into 
your Courier server from another webmail provider?

I was thinking about some columns in the password database.  Users can 
specify where their filter has put the filtered messages, where they put 
them in order to confirm they are SPAM, where they move HAM messages in 
order to re-process them by maildrop, etc.

What would be a bit more flexible is a user's callback script that is 
run whenever a user moves a message.
