Re: [Dovecot] Dovecot + Vpopmail quota issues

I made a bit of headway but not too much.

I discovered that the order of the namespaces is very important.

The reason why dovecot was updating the maildirsize file under Archive
was because the Archive namespace was defined first.

I now define the root inbox first and Archive second and dovecot
properly updates the same maildirsize file as vpopmail in
domain.com/user/Maildir/maildirsize

However, there are two key differences still:

1. Vpopmail does not calculate the storage under
   domain.com/user/Maildir/Archive when it updates the maildirsize file.
   This is exactly what I want. Vpopmail reports the proper size.

2. Dovecot DOES calculate the storage taken up by:
   domain.com/user/Maildir/Archive despite the fact that '/' is not my
   default separator.

I think vpopmail acts properly and calculates the file sizes in
properly formatted maildirs.

For some reason dovecot does not .. or am I wrong ?

I've tried many configs to get dovecot to ignore the Archive folder
but none of them works. The only thing that works is if I specifically
write the name of each folder in the quota ignore definitions.

If my structure is as follows:

domain.com/user/Maildir/Archive/.Folder1/cur domain.com/user/Maildir/Archive/.Folder1/new domain.com/user/Maildir/Archive/.Folder1/tmp

Folder1 is a proper maildir and Archive is a \NoSelect folder.

I want dovecot quota to ignore ALL the possible folders under Archive
without mentioning them one by one.

This works for example:

quota = maildir quota_rule = ?:storage=0 quota_rule2 = Folder1:ignore

This does not:

quota = maildir quota_rule = ?:storage=0 quota_rule2 = Archive:ignore

How can I get dovecot to ignore the quota for all the possible folders
under Archive ?

is different fr Quoting qmail@top-consulting.net:

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@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 ?
