What We Check

MX: Mail servers exist and, optionally, include your expected gateway.
SPF: Single v=spf1 record, a terminating 'all' mechanism and at most 10 DNS lookups (RFC 7208).
DMARC: A _dmarc policy is published, its enforcement level and whether aggregate reports (rua) are collected.
DKIM: A public key is published under one of the tried selectors.
DNSSEC: The DS record and signature chain validate, preventing 'Bogus MX' / DANE failures.

Findings are reported in Turkish, matching the output of the command-line tool.
