How to configure SPF, DKIM and DMARC records?

To secure your e-mail service and make sure that you won’t have issues with e-mail spoofing, you need to set SPF, DKIM and DMARC records for your domain.

  • SPF – An SPF record is enabled by default for your domain name in our DNS zone. You can modify it if needed from Site Tools > Email > Authentication.
  • DKIM – By default DKIM should be enabled. To disable DKIM for your domain, go to Site Tools > Email > Authentication > DKIM > Deactivate.
  • DMARC – this is a TXT record that practically tells the receiver to send an email to a particular e-mail address if he gets spam emails from a certain domain. The record is added from Site Tools > Domain > DNS Zone Editor, and should look like this:
_dmarc.domain.TLD IN TXT 18000 "v=DMARC1; p=none; rua=mailto:postmaster@your_domain.com"

change domain.TLD and postmaster@your_domain.com to the proper ones according to your case.

You can use custom SPF and DKIM values for your domains. You can add the records using the DNS Zone Editor in Site Tools.
