To secure your e-mail service and make sure that you won’t have issues with e-mail spoofing, you need to set SPF and DKIM records for your domain.
- By default, SPF is enabled and added to your domain’s DNS zone with Siteground.
- To manage the SPF record of your domain name, go to your Site Tools > Email > Authentication > SPF > Activate.
- By default, DKIM should be enabled.
- To enable DKIM go to Site Tools > Email > Authentication > DKIM > Activate.
