Cheers for the reply Big Dan, the banned addresses now amount to 85. I think your right enough because to ban the address you have to open the message. From now on I'll leave them and let them delete automatically or even delete them myself without opening them. I have a sneaky feeling someone has sold my Email address and now I'm getting these messages from all over the world. I also think it's a coincidence it started approx. the same time as I switched broadband supplier to Talk Talk. Once again many thanks for your advice. Bob.
