Start monitoring

What is SPF?

SPF (Sender Policy Framework) is a DNS TXT record that lists which mail servers are authorized to send email on behalf of cal.com. Receiving servers check the sending IP against this list; anything not listed can be rejected or marked as spam.

What is DKIM?

DKIM (DomainKeys Identified Mail) cryptographically signs outgoing messages from cal.com, letting receiving servers verify the message wasn't altered in transit and genuinely came from an authorized sender.

What is DMARC?

DMARC ties SPF and DKIM together for cal.com, defining what receiving servers should do when a message fails both checks -- and where to send aggregate reports so you can monitor abuse of your domain.
