mail_location in userdb inconsistent with imap and pigeonhole

[Ladislav Laska]

Hi!

I'm still fighting with lost mails and what I think is a locking
problem.

As I've lost some pretty important mails already, I decided to mitigate
my troubles by moving to maildir format, which should not be susceptible
to these problems.

I read the docs and wanted to test on my account, before I mess with all
the others and possibly break something. The way to do it seems to be to
do an override via userdb. I already have a passwd-file authdb, so I
uncommented those few lines in configuration, and added this to
my passwd-file:

krakonos:{SHA256}xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx=:1000:100::/home/krakonos:/bin/bash:userdb_mail=maildir:/home/krakonos/Mail

Now, I'm not really sure why it has to be prefixed with userdb_, but the
example in docs has it, and it seems to work.

I've attached the relevant part of a logfile, with some debugging
enabled, but in short:

Dec 10 18:39:22 ibex dovecot: imap(krakonos): Debug: Added userdb
setting: mail=maildir:/home/krakonos/Mail
[...]
Dec 10 18:39:22 ibex dovecot: imap(krakonos): Debug: maildir++:
root=/home/krakonos/Mail, index=, indexpvt=, control=,
inbox=/home/krakonos/Mail, alt=
[...]
Dec 10 18:39:52 ibex dovecot: lda(krakonos): Debug: mbox: INBOX
defaulted to /home/krakonos/.mbox/inbox


I'm confused why the last line chooses my old mbox over the new
location.

I'm even more confused by the fact the IMAP works fine, and as I connect
from mutt over imap, I can see empty mailboxes (the ~/Mail has only the
basic cur/new/tmp structure).

However, pigeonhole delivers into the .mbox, and not only if it's for
INBOX, but also for spam and others.

I read somewhere in the docs that the order is first try userdb, then
mail_location and namespaces override the rest. This might be the
problem, as I have:

mail_location = mbox:~/.mbox

namespace inbox {
  inbox = yes
  location = 
  mailbox Drafts {
    special_use = \Drafts
  }
  mailbox Junk {
    special_use = \Junk
  }
  mailbox Sent {
    special_use = \Sent
  }
  mailbox "Sent Messages" {
    special_use = \Sent
  }
  mailbox Trash {
    special_use = \Trash
  }
  prefix = 
}

Due to inbox=yes this would explain why inbox is using the default path in
mail_location. But why even the spam is delivered into the old mbox? And how do
I solve the problem anyway, should I just remove the namespace?

Anyway, it doesn't explain why the IMAP part and pigeonhole apply different
rules and show me different inboxes, which is probably a bug.

Thanks!
