I get the same spam email/message every day from the same domain, they just slightly change the email name before the ampersand " @ " (there are 20+ characters in the name) by one or two hex characters. If i choose "Block Sender" from my JUNK MAIL tab, it only blocks that variation, on that day!
When I select "Show full header" the sending/originating domain is the same for each daily spam email. I googled the domain's IP address and it is known for spam emails!
thanks TomFace for reply
