RFC 9989 note on p=reject
RFC 9989 cautions against p=reject for domains whose users post to mailing lists, and §7.4 requires receivers to treat p=reject as p=quarantine unless their own analysis justifies rejecting. For transactional or marketing-only domains, p=reject stays appropriate; mailbox domains should consider p=quarantine with sp=reject on non-sending subdomains.

SPF

mail.ru enforces a strict DMARC reject policy, instructing receivers to block unauthenticated emails. SPF is published with a soft fail policy (~all), flagging unauthorized senders without blocking them. A few improvements would strengthen mail.ru's email authentication posture.

Keep mail.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.

Well configured

Reject policy + valid SPF

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.
