Q: DKIM Add to DNS txt Record

Hi Folks,

 

I have a DKIM key to add and the service provider that I am using instructs me to put in the host name as "Host/Name: api._domainkey ".
However I cannot put underscore "_" in the server's DNS entry. So,is there any proper way to do this? I can successfully put SPF as a txt record though.


Any help is appreciated.

 

Best Regards,
Pyie

A:

You need to hand edit the DNS server file. As you have found the Server.app program does not allow this.

 

First temporarily turn off the Mac DNS server in Server.app

Then launch Terminal.app and edit the appropriate file in -

 

/Library/Server/named/

 

e.g. db.yourdomain.com

 

Then add a line in that file looking like the following but with your values.

 

_domainkey.yourdomain.com.               10800 IN TXT      "t=y; o=~; r=postmaster@yourdomain.com"

 

Note: You might have to do this both on your Mac DNS server and also on an external DNS server managed by your Internet provider, this depends on how your domain is setup.

 

Finally use Server.app to start your Mac DNS server again, it will then re-read the DNS files including the above addition.

    Thanks a lot! This solved the problem.
    This is what I did.


    I needed to put both SPF and DKIM to my DNS Record.

    For SPF is fairly simple,you can just use the server GUI.
    Now,left with the DKIM but my DKIM host name i"api._domain" and apple server GUI wouldn't allow me to put in the underscore "_".
    So,I go to /Library/Server/named/db.yourdomainname.com
    Use "sudo" to edit that file.
    At the last line(or wherver you want), I put the following
    "api._domainkey.mydomainname.com.      10800 IN TXT      "0=~" api._domainkey.mydomainname.com TXT "v=DKM1; k=rsa;t=s;p=restofthekey""

     

    *Note : My provider is elasticemail and they gave me one private key.
