Quota plugin creates IMAP folder

Hi everyone,

I have noticed recently that Dovecot creates lock directories under users' Maildirs which look like IMAP folders. This is bad since users will see IMAP folders that are not supposed to be there.

In my logs I see

dovecot: imap(...): Error: file_create_locked(/.../Maildir/.vsize.lock) failed: Is a directory

The directory in question

# ls /.../Maildir/.vsize.lock/ cur/ dovecot.index.log dovecot-uidlist maildirfolder new/ tmp/

so Dovecot seems to think this to be an IMAP folder.

I am using Dovecot 2.2.27 under Debian, built from source, the lock_method is set to fnctl, and the quota plugin uses the maildir method.

Can somebody advice me on how to fix this?

Best regards, Thorsten

This is a configuration issue, not a bug.

use

mail_home=/path/to/some/directory

mail_location=maildir~/Maildir

that is, make sure the mail location is under mail home (even for virtual users).

This is from my config

mail_location = maildir:~/Maildir

and in my userdb-ldap.conf

user_attrs =
...
=home=%{ldap:homedir},
...

Am I missing something?

So what does "doveadm user <uid>" then return as home?

Well, I have to scrub most data from the output, but it is what I would have expected

# doveadm user <user> field value ... home /path/to/home mail maildir:~/Maildir ...

Ah seems you have found a bug, apologies. =)

We'll look into it.

As workaround, you can either use VOLATILEDIR setting for maildir, or you can set maildir_stat_dirs=yes in config.

Thanks for picking this up and for the hints. Sadly the version I am running is slightly too old for VOLATILEDIR and stat is not an option for performance reasons, if I am reading the documentation correctly.
