dovecot - Feb 2010 - Virtual POP3 Inbox question

Hi,

I'm having trouble implementing the virtual pop3 inbox solution in 
Dovecot 1.2.x. As the following wiki page describes 
(http://wiki.dovecot.org/Plugins/Virtual) one should only set the 
inbox=yes flag for the virtual namespace which then flattens all 
mailboxes in the realmails/ prefix.
In the above example when I set the inbox=yes flag for the virtual 
namespace, the inbox in the realmails/ prefix gets left out for obvious 
reasons. How did the original author intend this to work?

Regards,
Jos

Yes.

Huh? No..

I think you're misunderstanding/misinterpreting something, but I can't
really think of what..

INBOX is a special mailbox. Setting inbox=yes changes nothing except
where INBOX's location is looked up from. No other mailboxes are
affected. Listing/opening RealMails/INBOX might or might not work,
depending on configuration. But that shouldn't be an issue, since INBOX
is accessed directly as INBOX.

Timo,

Thanks for clearing things up. I have finally figured it out (I
hope)

Well in order to list secret/INBOX I had to specify the INBOX location 
manually and use the dot separator scheme in a "/" separator setup.

mail_location = maildir:/mail/%d/%u/:INBOX=/mail/%d/%u/.INBOX

# Default
namespace private {
     separator = /
     prefix }

# Virtual
namespace private {
     prefix = virtual/
     separator = /
     location = virtual:/mail/virtual:INDEX=/mail/%d/%u/virtual

}

# Hidden
namespace private {
     prefix = secret/
     separator = /
     list = no
     hidden = yes
}

My folder layout:
.Drafts
.INBOX
.INBOX.test
.Junk
.Sent
.Trash


dovecot-sql.conf:
# Userdb is fetched with the password check as userdb_ extra variables
password_query = SELECT password, allow_nets, \
                 maildir as userdb_maildir, uid as userdb_uid, \
                 gid as userdb_gid, \
                 CASE '%s' WHEN 'pop3' THEN NULL ELSE
'yes' END AS
userdb_namespace_1_inbox, \
                 CASE '%s' WHEN 'pop3' THEN 'yes' ELSE
NULL END AS
userdb_namespace_2_inbox \
                 FROM users WHERE username = '%u'


# Only used when no password is checked for users
# eg. deliver
user_query = SELECT maildir as home, maildir, uid, gid, \
                 CASE '%s' WHEN 'pop3' THEN NULL ELSE
'yes' END AS
namespace_1_inbox, \
                 CASE '%s' WHEN 'pop3' THEN 'yes' ELSE
NULL END AS
namespace_2_inbox  \
                 FROM users WHERE username = '%u'

I'm using prefetch userdb so I had to put the namespace selection into 
the user_query as well.
