To get started with DKIM record:

  1. Publish your public key to your DNS record as a text (TXT) record. Check with your DNS provider to see if they allow more than 255 characters in the input field or not, as you may have to work with your provider to increase the size or to create the TXT record itself.

  2. Save the private key to your SMTP server / MTA (mail transfer agent).

A domain can have as many DKIM records for public keys as servers that send mail. Just make sure that they use different selector names.
