Hello Jimthedummy! My name is Janbaz, and I am an Independent Advisor.
I'm sorry to hear you're having this problem, and I hope I can assist you to find a satisfactory solution.
One of the possible reasons why you are encountering this problem is that there are corrupted cache/cookies/browsing history stored in your browser. As an initial troubleshooting step, I recommend that you clear your browser's cache/cookies/browsing history.
It's conceivable that the spam emails you're receiving in your inbox employ the "spoofing" technique, which involves forging the email header to conceal the genuine sender's details. Due to this, it may be challenging to block the sender using conventional techniques, such as blocking by email address or domain.
You might also be able to set up a rule to move emails that satisfy certain requirements directly to your Junk Email bin in addition to banning by email address or domain. This is how you accomplish it in Outlook:
- Choose "Rules" > "Create Rule" from the context menu when you right-click on a message that you wish to block but that doesn't show the From address.
- Choose the "Subject includes" or "Message body contains" criteria you want to use in the "Create Rule" dialog box to mark the message as spam.
- After choosing your criteria, check the box next to "Move the item to folder" and choose "Junk Email" as the destination folder for the message.
- To create the rule, click "OK".
