check_smtp_tls
shallowai.intodns/scanner · Verify this server
Live check of every MX host: opens TCP 25, runs EHLO + STARTTLS, validates TLS certificate trust chain, hostname match, expiry window, advertised EHLO capabilities, plus PTR and forward-confirmed reverse DNS. Read-only — connects and quits without sending mail. Returns per-MX cipher/version, cert SANs, expiry days, FCrDNS verdict, and STARTTLS-required flag. Use to verify inbound mail TLS posture; pair with check_mta_sts for the policy layer. May be slower (10-30s) due to live SMTP handshakes. No auth.
