I'm getting hundreds of spam emails with Bit Coin subject and Anti-Virus Renewals plus others informing me that I have made a payment of some sort that I need to verify. These emails have one thing in common and that is the nature of the email address from which they were sent. These adresses are all totally random gobbledegook. That is random combinations of letters and numbers. Why can't these be filtered out? Surely these addresses can be tested for their authenticity as any attempt to reply results in failure.
Examples:
Bit Coin Millionaire <atxibou@impues.atrooitrps.com>
B T C <jejectz@fuldes.gapires.com>
Bit-CO!!!n Loophole <diewmct@jehro.thigne.com>
Confirmation-Needed <ginizzaw@muneta.crantyper.com>
