where should i add dkim records when using custom name servers?

Question

I have recently setup mail server on ubuntu14.04 using postfix, dovecot. I am very confused about adding dkim records. Every tutorial i have followed is saying i should add dkim at domain registrar but i am using custom nameserver like ns1.mydomain.com & ns2.mydomain.com so there is no option to add txt records now. So my question is where should i add dkim. BTW i am also using bind9 on ubuntu

For DKIM records to work need to be added to whatever namer servers are authoritative for your domain so that, like any other public DNS record, those records will be available to any internet system that needs to query them.

When you host your own DNS, yes that will be your own servers. If your DNS is managed by somebody else, you will need (to ask your provider) to add them at whatever provider you use...
