This property specifies to what extent this behavior should be enforced. The default :value:`balanced` link handler will open links to the same host directly in Thunderbird, everything else will be opened in the user’s default browser. A :value:`relaxed` link handler will open all links inside of Thunderbird, a :value:`strict` link handler will open all links in the user’s default browser, except links to the same page.
