Hi Daemach,
In the latest version of SmarterMail, Automated Forwarding can be enabled/disabled at the system, domain and user level. If the card is not showing when a user goes to Settings > Account or when a Domain Admin goes to Domain Settings > Accounts > [user], it must be enabled for the domain at the system level. Below are some screenshots that should help you out. I've asked that the KB article be updated to better note this.
Log in as the System Administrator, go to the Manage icon and edit a domain. On the Features card, enable "Automated Forwarding".
Manage the domain or log in directly as a Domain Administrator. Go to Domain Settings > Accounts and edit a user. On the Forwarding card, enable "Enable Automated Forwarding".
When both of these are enabled, the user can log in and go to Settings > Account and find the Forwarding card.
These settings are also available in the templates for Domain and User Defaults, so you can set these defaults to be enabled or propagate changes among your domains/users.
I hope this helps!
