MWEB offers a function that is supposed to block individual addresses - rather like the one on this forum. The address is not changing.
You clearly have no idea on how spam filtering/smtp mails work.
Is called spoofing - I can send a mail to you and make it appear from [email protected] but its actually sent from [email protected]
As its a spoofed address blocking [email protected] won't block the email. You would need to blacklist [email protected]. But if you do that the next spam you get from them will just be from [email protected]
