@ einride - LSMail has to be configured, check your themevars file and you will see ;; LSMail.section and fill out the details. Ideally, you want to create a config file in your personal folder that it is trying to include with your mail settings so that you don't have to re enter them everytime you install a new version of litestep.

If you also look at your theme.rc file there is some more settings for LSmail, like setting location if you only have one email account etc.
