Once or twice a day I receive an e-mail from an alphaneumeric email address. I have never opened the emails, I simply delete. If you right click on the email you can see that it is a computer generated email and probably fishing. How do block this from my inbox?
Best way is to mark it as spam whenever it gets to your Inbox. That will help train the filters over time. You could try setting up a filter for it, but spammers will constantly change their messages to dodge filters.
