99.9999% of the time the sending address has been hijacked - if you look deep into the email's header you might see the real originating address, which is usually china, saudi arabia, russia, etc.
the only way of blocking such spam is to set up a filter in your email app, to block the title and/or body content.
NOTE: - if you mark the email as "spam", you are blocking the visual email address! you might want to receive email from that address, some day!
