Mail settings tabs are not working when accessed directly from the dashboard

short description

Users cannot access autoresponder and other tabs settings when viewing email settings directly from the dashboard. Clicking on the tab results in a 404 error in the console. Tabs still works if you go to "Email Mailbox" section first, instead of selecting the email account directly from the dashboard. This only affects users, not the admin.

correct behaviour

User should be able to see the tabs for other settings.
