I get this error when I send to an announce list. The list contains only rhodewalt.com addresses (each in daily use), and I’m sending from the Dreamhost webmail interface.
I believe I need to set up an alias to point to the announce list, which I’ve tried, but I can’t find the right settings. Thanks for any suggestions.
