I can't get dovecot to ignore a certain directory/namespace when
calculating quotas.
I am running dovecot 1.2.16 with vpopmail configured for quotas.
I use the dot (.) as my separator and my user structure is as follows:
../domain.com/user/Maildir for all the user directories
I also have for each user:
../domain.com/user/Maildir/Archive which is a symlink to a NFS
mounted partition that holds read-only archives
In dovecot.conf I have defined them as follows:
mail_location = maildir:~/Maildir
namespace private {
separator = .
prefix = ARCHIVE.
inbox = no
hidden = yes
list = yes
location = maildir:~/Maildir/Archive
}
namespace private {
separator = .
prefix =
inbox = yes
}
This works very well, in as much as I see the Archive namespace and
its folders.
The problem arises in the fact that Dovecot insists on calculating the
'Archive' namespace/directory storage towards the total storage used.
My Quota configuration is as follows:
auth default {
mechanisms = plain login digest-md5 cram-md5
passdb vpopmail {
args = webmail=192.168.1.12
}
userdb vpopmail {
args = quota_template=quota_rule3=*:backend=%q
}
...
}
plugin {
quota = maildir
quota_rule = ?:storage=0
quota_rule2 = Archive:ignore
quota_rule3 = ARCHIVE:ignore
}
From what I've read, this is supposed to use the maildirsize file
when available or otherwise return no quota. It worked just fine
before this new Archive namespace.
For a certain user, vpopmail writes the 'maildirsize' file in
../domain.com/user/Maildir/maildirsize and it contains the correct
value ( without the /Archive directory ).
The problem is that for some reason, something ( I suspect dovecot )
writes a new maildirsize file in
../domain.com/user/Maildir/Archive/maildirsize which also contains the
size of Archive. Subsequently, Dovecot adds the two of them up and
usually throws me over quota.
To test, I have emptied the maildirsize file under Archive and changed
its owner to root (perms are 755 ) so that nobody but root can write
to it. Dovecot complained right away about it:
Jul 19 12:55:21 pop1 dovecot: IMAP(user at domain.com):
open(/home/vpopmail/domains/B/domain.com/user/Maildir/Archive/maildirsize)
failed: Permission denied
Despite passing the quota responsibility to vpopmail it seems that
Dovecot still tries to update that file.
And finally the question... How do I get dovecot to not calculate a
quota for that directory/namespace ?
