Hello everyone,
I'm setting up a Postfix+Dovecot stack with virtual domains and public
mailboxes.
I set up a shared mailbox "off...@mydomain.com" as described in the
Dovecot Wiki [1], that is:
- I created the directory "/var/mail/mydomain.com/public/" and inside
it I created the ".office" mailbox;
- I added an appropriate ACL to allow the account
"presid...@mydomain.com" to read and edit that mailbox under a public
namespace;
- I added a Sieve script to handle delivery to the public mailbox (its
location is /var/mail/mydomain.com/public/.office/.dovecot.sieve).
Some other relevant details about my configuration:
- The backend used by Postfix and Dovecot to handle virtual
aliases/domains/maps is a MySQL database. Since the virtual user
table is used by other applications as well, I decided to keep it
"clean" and to make use of another "virtual mailboxes" table (see
/etc/dovecot/dovecot-sql.conf.ext below). The password_query setting
returns only results from the virtual user table (so that only real
users can authenticate on the IMAP server), while the user_query
setting returns results from both the virtual user and the virtual
mailbox table (so that dovecot-lda can choose the correct mailbox).
- The queries saved in password_query and user_query return the correct
results when executed manually: the home directory for the
"off...@mydomain.com" virtual mailbox is set to /var/mail/mydomain.com
/public/.office.
- Delivery from and to the "presid...@mydomain.com" account is regular,
and that account is able to access the "off...@mydomain.com" virtual
mailbox (I have tested this by speaking IMAP to the server and by
performing a manual check using Thunderbird).
I encountered a problem with this setup: when I send a message to the
"off...@mydomain.com" account, the Postfix logs say it is correctly
delivered via Dovecot, but the Sieve script says it can not find the
folder "Public/.office". As a consequence, Dovecot creates a new Maildir
in /var/mail/mydomain.com/office and delivers the mail there instead of
saving it in the correct directory (/var/mail/mydomain.com/public/.office).
Is there something I set incorrectly in my configuration? What is
causing Dovecot not to recognize the correct mailbox during delivery? Is
there a way to list all mailboxes seen by dovecot-lda itself?
Thanks,
Alessandro Menti
