What is an email server setup check?

This tool allows you to comprehensively check a domain's email settings. We check for necessary DNS records and the availability of mail servers.

What checks are performed?

  • MX: Identifies the servers responsible for receiving mail for the domain.
  • A: Checks the IP addresses of the domain and mail hosts.
  • SPF: Checks for rules that allow specific servers to send mail on behalf of the domain.
  • DMARC: Checks the mail handling policy for messages that fail SPF or DKIM checks.
  • SMTP: Checks the availability of port 25 on mail servers.
  • PTR: Checks reverse DNS records for the IP addresses of mail servers.
