[Dovecot] Excluding ALT maildir from showing in main INBOX

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 Przewlucki
