SPF, DKIM og DMARC
DMARC ensures that an email comes from the correct email server, and that it is not manipulated along the way. DMARC makes it hard for hackers to misuse your email domain; for instance, to send fake emails from your email address to trick your users into thinking that the email comes from you. This is like a postal worker checking your identity every time you send a letter. (( DMARC indicates whether your domain is being misused and whether your emails are arriving at their destination without problems.)) (( DMARC builds on the DKIM and SPF security standards, which are important additions to your email hotel.)) The more domains that enable DMARC, the greater the benefit to the entire internet community: This means cleaner inboxes for everyone, with fewer fake emails and phishing attempts..
