Spam Mails

Hi, can anyone help me with following question? I get loads of spam every day and some are very consistent domains. How do I filter specific domains permanently so that it never enters my mail box. I am using MAC. Thanks

Normally, SpamSieve will learn to recognize these domains automatically. However, if you want to be sure that all those spams are caught you could open the Blocklist window and create some rules of the form “From (address) Ends With @domain.com”.
