dkimdomain-name-systemgodaddy
I am trying to understand how I should write my DKIM key in GoDaddy. What I wrote in the picture is my guess but I will then add my DKIM Key to sendmail and if I'm note sure this one is right I'll probably bang my head for hour in case of an error figuring out which is wrong.
This question is about the Host TXT Value part and brackets or selector conditions
let's say my domaine is goomoo.co and my DKIM key is ABC and I want one DKIM Key for the whole domain.
v=spf1 include:_spf.google.com include:otherdomain.com ~all
There's no restriction against including multiple names in a single entry; Hotmail, for instance, takes this to extremes. Note that multiple includes, or nested ones, need to stay under the limit of 10 total DNS lookups for the whole SPF check.
In short, you can't make the @ record a CNAME without deleting all other resource records for @, and you can't do that since some (like the NS records) are required for proper DNS functionality. This is one reason why providers such as Heroku tell you not to use naked domain names.
You will need a host to perform the HTTP redirection from example.com to www.example.com for you, to which you will point A (and AAAA) record for @.
If your DNS is hosted with GoDaddy, then they have a free service that will do this for you. In your GoDaddy domain manager, look on the left hand side for "Forwarding" and click "Manage". Then set it to forward example.com to www.example.com and update your DNS to support the change. You should leave the Advanced Options at their defaults.
