That I know.  Though since it is using a mysql database of users, I 
COULD add a column designating this.  But it would be difficult to 
maintain.  Better perhaps for dovecot NOT to be so nice to move the 
messages and leave that to the client.

Well ***SPAM*** is added to the subject.  And it seems that dovecot is 
being really nice to act on that and move it.  Now I have to remember 
what I did to configure this and unconfigure this.  I did much of the 
work long ago, set it aside, built a new box,,,  So now I am learning 
what I did.

I only have 12 users.  Small time, I know.  And some have 1000 flagged 
messages per day.
