What to review

Review the available observations below. Unavailable evidence prevents a complete assessment.

Public DNS; up to 2 inbound MX hosts, 5 public IPv4 addresses for IP blocklists and 3 for PTR. STARTTLS and TLSA concern the primary MX. IPv6, actual sending IP, DKIM and real message placement are not measured by this watch.

STARTTLS

No successful handshake observed

Connection failure, policy, and temporary network errors can prevent measurement. This alone does not prove TLS is disabled.
MTA-STS

Policy observed · enforce

TXT discovery: ok · STSv1 record observed. An HTTPS policy was retrieved. Full policy validity and all MX matches are not certified.
DANE / TLSA

No TLSA record observed

Presence check on the primary MX only; DNSSEC and certificate matching are not validated.

DNS records, explained

Observed 2026-10-26 12:34 UTC. These are the exact owner names queried.

A · inctoo.de

IPv4 destinations for this DNS name. An address change can reflect a CDN or load balancing; it does not by itself prove a hosting move.

167.233.38.44

AAAA · inctoo.de

IPv6 destinations for this DNS name. They do not identify the IP that sends your email.

1 value(s) shown

Show observed values

2a01:4f8:1c18:43cd::1

MX · inctoo.de

Servers advertised to receive mail for this name. Lower numbers have higher preference. They do not identify your outgoing sender.

1 mx10.inctoo.de

NS · inctoo.de

Name servers published for DNS delegation. Check intended DNS changes with your domain operator.

SOA · inctoo.de

Zone administration and refresh settings. The serial identifies a zone version; it is not necessarily a timestamp.

CAA · inctoo.de

Published restrictions on certificate issuance. Presence alone does not prove HTTPS is configured correctly.

No record returned by the checks completed

TXT · inctoo.de

Text declarations, including SPF and domain verification. A verification token is not evidence that a mail or SaaS service is actively used.

Public recursive DNS observations, up to 24 values per type and 512 characters per value. TXT verification tokens show a published claim, not proof that a service is currently used. A/AAAA describe this DNS name; they do not establish the sending IP or a hosting migration. No DNSSEC validation or complete zone enumeration is claimed.

Compare saved snapshots

The comparison uses saved observations; the exact change time between them is unknown.

The resource-record values available in both snapshots are the same. This does not prove there were no changes between observations.

Observation history

Up to 30 daily snapshots are retained. Missing days are not filled in; a gap is not evidence that records stayed unchanged.
