filter by reply address
The filters fail on spam when the spammer fools around with the "from" address field to trick the filter by not matching the actual sender address. Instead, the "reply" address is shown.
Here is an example in quotes:
"From: Health Secrets Reply.FvUYdCa@KaZbUjN.goverritoric.com"
We need the "from" filter to also apply to text contained in the "reply" portion of their address. This spammer is flooding my inbox using different prefixes. If I could filter by "goverritoric" it would catch every one, and I could send directly to trash.
If we are looking to improve the filtering, could you also add filtering on the "dmarc" section of the "Authentication-Results" (as shown in the raw message view) which would also catch the spam domain the spam is coming from.

Hi there! Sorry to hear about the issue. We do have a way to block based on words contained in the sender name: https://help.yahoo.com/kb/block-unblock-email-addresses-yahoo-mail-sln28140.html. When selecting "From" we must also check "contains" and there you can put the desired word. If more assistance is needed, please feel free to check help.yahoo.com.

GMAIL can block this spammer. Why cannot Yahoo mail???

This spam source has figured out how to bypass the user filters. They keep appearing as new messages that get past Yahoo auto-spam detection. Several daily (times) every email user = huge amounts of spam that Yahoo is not filtering.
