What is correct syntax for adding an email domain to Blocked List in NIS v22?
I get spam from assorted addresses in domains like @eku.edu and @eagle.com and I want to block ALL e-mail from those domains, but the Blocked List in the spam settings of NIS v22 (latest version, I think) doesn't seem to work. I suspect it's a syntactical problem. How do I block a whole domain? My settings are shown in the attachment.
