How to exclude a certain email from Scam-detection?

[pstover]

When I got email from a certain email address then Thunderbird always thinks its is scam and shows a red banner.

Ok, I can click "Ignore" in the context menu.
But it does not help on the long run.
The next time when I got an email from the same email address it is categorized as scam again.

How can I permanently exclude a certain email address (or domain) from being identified as scam?
Is there a whitelist or similar?

The Scam detection functionality is flawed and, as you can see, unreliable. The recommendation on these forums is to just switch it off. That's under Tools->Options->Security->Email Scams.
