Blocked email still coming through

There is not really an "Allow List" on Mac Mail. You have to set up a Rule, just like you do with exclusions, to "allow" particular addresses that may or may not be blocked to end up in your Inbox. And none of your other suggestions are applicable here in terms of the original question, which is why are we receiving opened emails from blocked senders with a notification saying the email is from blocked sender?

Regards your explanation...

I received repeat emails from senders I've blocked. They are all spam. I will sometimes see two or three on the same day and all are in my Spam folder with "Message from blocked sender"

-Senders are NOT on my allow list

-Junk mail filtering IS turned on

-Timing is not an issue... I don't expect immediate results, but I don't expect to receive mail today from a sender I blocked yesterday

-The blocked sender is NOT in my Contacts

Bottom line... blocking senders just populates the Spam folder, not the Trash. And this is inefficient because Apple does not do a very good job of differentiating emails from occasional correspondents vs. true spam. So, I have to inspect the 100-150 'blocked' emails in my spam folder to ensure a false positive for spam is dropped in there.

UPDATE: After following my above toggle switch solution, the problem is still happening. Even after the Apple tech person assured me the problem would be solved. I'm still getting messages in my Inbox that say "This message is from a blocked sender." Ugh. Back to the drawing board.

Why does apple even allow the messages to come through?!

You imagine incorrectly. My "rule" clearly says "Move to Trash." But they're still showing up in my Inbox.

Than it's not doing it's job and successfully tormenting it's users. This is the only email service that does this, and the issue is coming from a company with the biggest budgets to fix it.

So please keep thing in the correct Context

Technically, these are not rules created by the User ( @ Buffster )

I apologize I used the wrong term "rule". My response was to Luis S., who suggested the person had not set their toggle to "Move to Trash" when an email from a blocked sender comes in.

Didn't work for me. Running iMac M1, Sonoma 14.5. I may just switch to Gmail

My only two options…leave in the inbox or move to trash, which is checked…but it doesn’t! So frustrating!
