How to configure DKIM settings in DNS?

Posted on October 31, 2017

Hi, I’m trying to configure DKIM settings to stop bouncing of my emails from Amazon Simple Email Service to my clients on Hotmail. Amazon tells me to create certain CNAME records to configure DKIM:

xxxx._domainkey.lockd.co.uk to xxxx.dkim.amazonses.com and your DNS console doesn’t allow me to do that. There’s an error message telling I cannot refer it to external domain or so. The possible solution is to move DNS from you to Amazon but I hope there’s another way. Any suggestion?

Hello, @avshaf

If you’ve already generated the DKIM you just need to enter in the DNS zone from the control panel.

Add the public key to the domain’s DNS records

Copy that key and add a TXT record to your domain’s DNS entries:

Name: mail._domainkey.example.com.

Text: "v=DKIM1; k=rsa; p=MIGfMA0GCSqGSIb3DQEBAQUAA4GNADCBiQKBgQC5N3lnvvrYgPCRSoqn+awTpE+iGYcKBPpo8HHbcFfCIIV10Hwo4PhCoGZSaKVHOjDm4yefKXhQjM7iKzEPuBatE7O47hAx1CJpNuIdLxhILSbEmbMxJrJAG0HZVn8z6EAoOHZNaPHmK2h4UUrjOG8zA5BHfzJf7tGwI+K619fFUwIDAQAB"

Please note that the DNS changes may take a couple of hours to propagate.

Hope this helps!
