[Dovecot] Excluding ALT maildir from showing in main INBOX

[Tomasz Przewlucki]

Hi, 

I've setup dovecot 1.2.7 with dbox mail storage and ALTernative
(additional) mail directory + expire plugin and expire_altmove working
properly. 

grep from .conf: (
dbox:/var/spool/mail/%n/MAIL:INDEX=/var/spool/mail/%n/INDEX:ALT=/var/spool/mailarchive/%n/MAIL
) 

What i would need now is excluding all folders and messages from "ALT"
maildir from default view (so they will not show in INBOX and other
standard folders. 

I would like to create namespace or virtual folder and
include those ALT maildirs as so called Archive (f.e. prefix). 

Is that
(excluding ALT from default view) possible ? 

Best Regards, 

Tomasz
