2 DKIM in the same domain

Question

We use an external service for our newsletter, which required tracking the installation of DKIM in our gipote.dk domain:

_domainkey.gipote.dk. 43200 IN TXT "o=~" default._domainkey.gipote.dk. 43200 IN TXT "k=rsa\; p=MIGf...ibnrkoqQIDAQAB" 

(I cut the public key for readability ...)

However, we also send an email from our own server, which I would also like to sign.

Is it possible to have more than one public key TXT record in our gipote.dk domain? If so, how to configure it?

EDIT: I do not have access to the private key used by the newsletter service. Therefore, I cannot just install this on my own server.

Answer 1

I found out that the answer is YES :-)

"default" can be easily replaced with another selector name.

Answer 2

Yes, you can change the default value to another selector. BUT, if you make the domain it is located on, it will no longer check the domain.

You need to add a second NOT CHANGE key that exists using Google mail, you will end up

default._domainkey "v = DKIM1; k = rsa; p = MIIBIj ....." google._domainkey "v = DKIM1; k = rsa; p = MIGfMA ......"
