Email authentication check

yandex.ru

This check reviews the domain's email authentication setup to help protect against spoofing and phishing.

All data is public, sourced from DNS Last checked about 20 hours ago
Needs attention

yandex.ru has email authentication in place, with important improvements still available.

Some protections are present, but tightening the policy, reporting, or sender authorization would improve resilience.

MTA-STS and TLS-RPT are optional, but they protect inbound mail against transport downgrade attacks and give visibility into TLS delivery failures.

Protect inbound transport

Receiver Shield helps deploy, monitor, and safely enforce MTA-STS and TLS-RPT for yandex.ru.

Start monitoring

yandex.ru has a DMARC record in monitor-only mode (p=none), which tracks authentication failures without blocking them. SPF is published with a soft fail policy (~all), flagging unauthorized senders without blocking them. A few improvements would strengthen yandex.ru's email authentication posture.

Keep yandex.ru protected automatically

This check is a snapshot. DNS records drift when providers change, teams edit records, or unauthorized changes slip in. DMARCTrust watches the same authentication layer continuously and tells you when something moves.

DMARC report processing

Aggregate and failure DMARC reports are received, parsed, and turned into sender visibility without manual XML handling.

DNS change alerts

DNS checks run every 5 minutes for monitored domains, with email alerts when DMARC, SPF, BIMI, TLS-RPT, or MTA-STS records change.

Receiver Shield for inbound

Deploy, host, and safely enforce MTA-STS and TLS-RPT when this checker finds an inbound transport gap.

What we check

DMARC policy and alignment, SPF record and includes, BIMI logo and certificate, and inbound transport security with MTA-STS and TLS-RPT.

Why it matters

Healthy authentication improves delivery and blocks spoofing. Major inbox providers increasingly expect DMARC and aligned SPF or DKIM from senders.

What you get

Syntax, policy, reporting validation, include analysis, alignment interpretation, and clear setup guidance for every result.
