Email providers normally provide for an email to be marked as not spam and for filters to have the same result. This doesn't seem to be a browser issue.

You previously posted a similar question in the Thunderbird support forum, but didn't seem to have heard of Thunderbird, so you likely have a problem with an online email service.

• /questions/1406321 why is all my safe senders coming in to the junk email folder?

What email service do you use ? You will have to check their FAQ or contact them for support.

I posted this question on the Firefox tab, I have no idea how it got on the Thunderbird support forum? My email is terry.penton@hotmail.com and that is where my problem lays at. All my mail keep coming in to my junk mail, than I have to sort it out and put it in my inbox where all my safe senders are at. I don't understand why. I didn't have this problem until I was forced to upgrade to windows 11. Help please cause Microsoft won't HELP.
