This is a few days I'm trying to understand the implementation of email management in the version 4.0.1a ... Of course, email is very important in a CRM... when it works.

My conclusion is this option do not work and makes the users management really hard to manage... It is impossible to delete users when this has been made by the email managing ("Manage Mailboxes") because, you will find the users for the email in the same interface of the users management ... Hum, this part of the soft is really not "user friendly".
