How to setup SPF and DMARC

Understanding SPF and DMARC

SPF and DMARC are like security badges and policies for your mailbox.

  • SPF tells other email servers which machines are allowed to send emails for your domain.
  • DMARC sets clear rules for handling suspicious messages and helps you track any attempted abuse.
