Missing Menu items for Kmail Korganizer

[phd21]

Do I have to manually create these?

These menu items are hidden by default. So either create the manually or restore system default menu with the menu editor (right click on the menu -> edit applications)

I also had to install the gufw firewall? Maui does not come with a firewall installed?

Gufw is just a graphical user interface for the package filter iptables that comes preinstalled on Maui aswell as most other Linux Distros by default.
