Problems

!

Policy: quarantine

DMARC · DMARC policy is set to 'quarantine'. Consider upgrading to 'reject' for stronger protection once you've verified legitimate emails are passing authentication.

#4
!

No key under common selectors

DKIM · The _domainkey name exists but no DKIM key was found under the common selectors. Selectors are provider-specific; check yours with -selector.

#7
!

Hosts without IPv6

MX · The following MX hosts could not be resolved to IPv6 addresses: mx0.mail.ovh.net, mx1.mail.ovh.net, mx2.mail.ovh.net, mx3.mail.ovh.net

Signatures expire in 109h0m0s

DNSSEC · DNSKEY signatures expire at 2026-10-26T18:05:27Z (in 109h0m0s). Check that re-signing works.

#21
!

Not configured

TLS · MTA-STS is not configured, so other mail servers fall back to unencrypted delivery when TLS fails or is stripped by an attacker. Publish a _mta-sts TXT record and a policy at https://mta-sts.<domain>/.well-known/mta-sts.txt.

#32
!

No certificate (a=)

BIMI · The logo is published without a Verified Mark Certificate. Gmail and Apple Mail only show BIMI logos with a VMC or CMC; Yahoo shows it without one.
