Frequently asked questions
What do SPF, DKIM and DMARC do?
SPF lists who may send mail for your domain, DKIM cryptographically signs messages, and DMARC tells receivers what to do when checks fail — together they stop most spoofing.
Why is my DMARC "p=none" a problem?
"p=none" only monitors; it doesn't block spoofed mail. Move to "quarantine" then "reject" once your legitimate senders pass.
