dovecot - Apr 2009 - Public mailboxes configuration to receive mails

Hello,

I would like to know how to use Public mailboxes in my Dovecot 
environment (dovecot 1.2.beta4)
 
Currently my dovecot server is only used for mailbox user. The Postfix 
master.cf is configured with the following line:
"dovecot  unix -  n       n       -       -       pipe  flags=DRhu 
user=vmail:vmail argv=/usr/libexec/dovecot/deliver -d ${user}"
 
Both dovecot and postfix use LDAP requests for authentication and users 
data retrieving. 
 
However  I don't use userdb database to get the users home directory but 
an userdb static instruction :
"args = uid=vmail gid=vmail home=/data/maildir/%1Lu/%Lu
allow_all_users=yes"

I have configured my dovecot.conf to create a namespace Public, and it 
works fine: an user who have read/write access(ACL) to a public mailbox 
can subscribe to it and read/copy mails. 
My problem is to deliver mails in this public mailbox. I don't know how 
to do it.
 
Therefore, first question: is it possible to deliver mails to a public 
mailbox through the LDA/Postfix ?
If yes, please could you tell me how to configure LDA/Postfix and 
Dovecot in order to accept and deliver mails to users mailboxes and to 
public mailboxes ? 
I assume that the main modifications should be done in the master.cf of 
Postfix. Could you please specify and clarify what modifications are 
required ?

Find below my dovecot -n output and dovecot-ldap.conf.


Thank you in advance for your help and your feedback.
Regards
Didier F.

Yes, as long as the user running deliver has permissions. Either you'll
use a Sieve script that writes to the wanted mailbox or you give -m
parameter that specifies the mailbox. In either case you need to make
deliver write the mail to the public mailbox, e.g.:

deliver -m Public.somebox

You didn't tell what mails you want to the public mailboxes.. Perhaps
you should create a dedicated user that receives mails for the public
mailboxes and then a Sieve script that redirects them to the correct
mailboxes.
