The last post I saw about this was from Nov 2014 and it was closed.
I want to make sure to add another request for TXT records to be large enough to fit a 2048-bit DKIM key. This seems like an oversight as this is now the required size for DKIM for GMail authentication.
I have to say that I was disappointed with the response that a different DNS host be used. I love hover over GoDaddy, but GoDaddy has gotten a lot better lately and they support this size of TXT record.
