MX, SPF, DKIM and DMARC: the e-mail records

Four DNS records make a domain's e-mail work. MX says where e-mails sent to sendgrid.net arrive; SPF, DKIM and DMARC let mail servers check that an e-mail claiming to come from sendgrid.net was really sent by this domain, which protects it against spoofing.

sendgrid.net  MX  10 mx1.sendgrid.net.
sendgrid.net  MX  20 mx2.sendgrid.net.

sendgrid.net  TXT  "v=spf1 mx include:_spf.google.com ip4:192.0.2.10 -all"

google._domainkey.sendgrid.net  TXT  "v=DKIM1; k=rsa; p=MIIBIjANBgkqhkiG9w0BAQEFAAOCAQ8AMIIBCgKCAQEA…"

_dmarc.sendgrid.net  TXT  "v=DMARC1; p=quarantine; rua=mailto:[email protected]; adkim=r; aspf=r"
