Ability to permanenty update junk controls for a specific sender in Thunderbird

[dd]

Is there a way to update the junk control setting for a specific sender?

I receive a monthly health report from my car's app service.  Problem is that it always ends up in the Junk folder.  I have repeatedly used the "Mark As Not Junk" option via the menus and the "Spam" column indicator.  Each time the email goes back to my Inbox only to be resent back to the Junk folder within minutes.  I have been doing this for at least one year but to no avail.

Is there a way to edit the Junk Controls data to ensure that a specific sender is permanently not considered Junk/Spam?

If not, would it be possible to get a feature like that?

IIRC, I could add the sender to my address book/contact list but I would rather not have a bunch of "donotoreply" address book entries. I just want the Junk Controls to remember the sender in some sort of internal white list.

Thanks
