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 grammarly.com arrive; SPF, DKIM and DMARC let mail servers check that an e-mail claiming to come from grammarly.com was really sent by this domain, which protects it against spoofing.

grammarly.com  MX  10 mx1.grammarly.com.
grammarly.com  MX  20 mx2.grammarly.com.
