As a user logs into another instance, the user should be
created 
automatically in the dbmail_users table. However, the
dbmail_acl table 
is usually configured to be locked into a row being existent
in the 
users table. Either the user needs to login to that server
to create the 
record, or you the admin need to create a correct user on
that box 
before adding the acl. This would make constant changes/add
to acl's 
difficult and tedious. Once setup, I think it should work ok
provided 
that your proxy is doing things correctly and that when the
user is 
selecting a folder from a different instance that connection
is being 
done with the connected user's credentials.
