I’ve attempted to fill the TXT field in my DNS for the DKIM key. I’m getting a message that the field can only be 512 characters. These days you need a 2048 key. (1024 uses to be good enough) Anyway, there is a procedure to use tokens to fill in DNS fields in order to get around the problem. I was given this once by tech support and neglected to save it. I found a link for web page for the procedure, but apparently Sammy the Whale ate the page.
So I need the procedure to file a TXT field in DNS using a token. My recollection is you used curl from your server to do this, or maybe your PC.
