Not blocking blocked senders

Hello lrstacks,

Thanks for reaching out to us for support. It’s never fun when you’re still receiving emails from blocked senders, and we are going to do everything we can to help you. When you have a free moment, can you please tell us when you first encountered this issue and the version of macOS Big Sur that you currently have installed on your Mac?

Find out which macOS your Mac is using

Next, you can adjust the settings for what happens to the incoming email after you've blocked it. Go to Settings > Mail > Threading > Blocked Sender Options. From there you are presented with three options:

1) None: This turns off all email blocking.

2) Mark as Blocked, Leave in Inbox: This will allow the blocked mail to come to your inbox, but you will not receive a notification for it.

3) Move to Trash: Sends the blocked email to the Trash folder. You can empty the trash manually, or choose to have the trash empty automatically in your account settings.

Lastly, please check out the link below and let us know if this helps you, or if you have any questions.

If junk mail filters aren’t working in Mail on Mac

Thanks for using the Apple Support Communities.

Cheers!

This may or may not fixed the issue. Update to latest version Big Sur 11.4 and Test.

I just started using the blocked contacts a few weeks ago. It never moved my junk mail from blocked contacts to the trash even though I selected that option. I have selected enable blocked mail filtering and move it to trash. The contacts in my junk mail indicate that the message is from a blocked sender. I am using macOS Big Sur Version 11.4. Thanks

I have the same issue. They just end up in the junk folder and not the trash. I have changed my setting many times with no luck. I gave up. I now just have mail delete all junk at end of day to clear them all out.
