Hello, I am receiving a lot of spams from emails which are using free domain. I am working only with companies if they are using paid domain. So I want to add free domains (.tk , .ml , .gf .....) extensions into SpamAssassin Spam List. Is there a way to do that?
I know how to block all addresses with one domain, example:
*@example.tk
But I want something like this:
@.tk
