You are wasting your time trying to block spammers. If it was that easy to stop spam the spammers would have gone out of business long ago. The spammers constantly change the email address to avoid it being blocked.
The email address will have been "spoofed" to hide the real email address so the email address that you see is not the email address that the email is originating from. You would need to look at the emails headers to see the genuine email address that sent it.
Do not open any emails that you suspect are spam as opening them just alerts the spammer that your email address is active. Just mark them as spam. Eventually the spammers will move on and /or the BT spam filters will catch up and block them.
