shared folders not working with . separator

Hi,

I've been trying this for weeks and never managed to get my mail client
to see shared folders.
Apparently imap_acl works fine as I can see these entries in the
dovecot-acl-list files and the correct entries persist in the client.
This is my first dovecot setup so I hope I've configured it right.
Everything else works beautifully, thanks.

Are they shown with telnet? e.g.

Are there folders shared from user1 to user2?

what does dovecadm acl get -u <user> -m shared.<user>.mailbox show?

doveadm debug -u user2 -m shared.<user1>.mailbox

Whats in your logs? Enable debug log and look for errors.

According to http://wiki2.dovecot.org/SharedMailboxes/Shared the "list = 
Children" hides the namespace from the imap list command, if there is no 
folder shared to the user. Try to set list = yes that should show the 
shared namespace in the imap list.

Also scroll down to shared mailbox listing, you should setup a dict so 
that dovecot knows which folders are shared.> namespace inbox {

you have two namespaces with the same name, put some string before the 
{'s.

like here.

Then check out the advices of Christian & Chris (telnet) as well

shared folders not working with . separator

Thanks, this helped.
I added namespace virtual and removed the virtual references from inbox
namespace and added list = yes so now I can see shared folder in the client.
There's still nothing in there though.

I followed Christian's advice, debug shows this very strange behaviour.
doveadm acl debug -u user1 at domain1.com.au shared.user2 at domain2.com.au
doveadm(user1 at domain1.com.au): Error: Mailbox 'com.au' in namespace
'shared.user2 at domain2.' doesn't exist in
/var/mail/vhosts/domain2/user2/mail/.com.au
There are no errors in the log.

This looks like a bug. I was seeing this before I got the shared folder
working when I saw dovecot had created these extra folders and added
dovecot-acl-list file there.
I suppose if I'd used the / separator, this would work fine, but there
was nothing about this on the wiki so I didn't expect this.
