Now, to unrelated ‘internet security’ voodoo. “Your email to the list did correctly add a DKIM signature, but it can't be authenticated because the "selector" given in the email header doesn't exist. That means your message cannot be authenticated.” This may have come about when I added Cloudfare because I had to switch DNS to them to get it to work. As I recall before I was going through my hosting company and all this mumbo jumbo was set up though them. I copied the DKIM gibberish to Cloudfare and we’ll see that that accomplishes. I do really think most of it is nonsense. If an SSL is so secure, why do I need to pay to get a new one generated every few years? How does it wear out? How is the new one more secure than the previous one? You pay money, they send you a text file that you copy/paste to the right box on the server. Mumbo jumbo. Right up there with the uselessness of changing passwords periodically. Jeff Birt
