At last, it works pretty well with major browsers :D
There is still a little problem about user selection in IE8 when using the shift key for multiple selection (don't know how to disable it).
At last something that works pretty well under firefox and with multiple selection possible (using Mootools HtmlTable.Select). There are some problems with IE and Chrome (the position: relative on td elements is not well supported).
Mootools update (1.3)

Checking limit when creating/updating a mailbox.
Work in progress:
* New domains admin page, all menus are now at the same level,
* Views, models and forms partial refactoring (better code organization).
Querysets used to populate form fields are more filtered (ie. the default admin is ignored, as the current logged in user).
see #92
More protection against errors that can happen when defining new permissions.
Work in progress. Multi selection is working (using shift+click) but I've made a mistake somewhere because the default shift key behaviour is not working anymore.
