[Dovecot] Dovecot + Vpopmail quota issues

[qmail at top-consulting.net]

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 ?
