Setting to contains noname.com will suffice, but that will block everyone who has that domain. If it's just from one person, I suggest using the full email id.

I forgot something about making up noname.com email reply address. I don't know every email address out there but hopefully I would never use google.com to block. I will do what you suggest full email id. Another question. Is there a way to automatically deleted spam or junk mails in my Block List so they do not go to span or junk folder they just disappear? Or an alternative would be to have them show up in Filter Log? Thanks

If your block list is on your web account, that would depend on how that email provider handles the issue.
