I keep receiving spam emails with a format that is difficult to block. The sender will only be identified as a single word or phrase. When I click on email properties a domain name is nonexistent. There is never an @domain.com. The spam blocker in my Outlook doesn't recognize it as an email address. When I reply to the email to get the email address I get the initial phrase with a semicolon a space and then an @domain.com. A recent example is an email from Your Christmas Score. When I hit reply YourChristmasScore; @mars.spinnerexpress.com is what appears. This is obviously spam. Why doesn't my AVG spam protection catch this?
