shared folders among different virtual domains

[Pierre Moermans]

Hello list,

I'm using cyrus-imap (2.2.7) with virtual mailboxes and virtual domains.
I have succesfully set up folders shared by users of the same domain.

I would like now to have folders shared by users of different domains. 
The problem is that , whatever the ACLs, the shared folders are only 
seen by people of the same domain.

For instance, I would like to have lahidalga at lahidalga.net shared among 
*@lahidalga:net and pierre.moermans at pm-soft:be.

How can I do that ?

Thanks,

Pierre
