Spam email but I can not add to Blacklist

Spam email but I can not add to Blacklist

Hello,

I have open a ticket about same problem previously but still troubling with spam emails. 
The sender address is not correct email format, so it is not possible to add blacklist. 

Pishing sender addresses like: "office@koser" or "amazon@localhost"
Please advice about how to block this rambling spammers
Thanks
emre
