DMARC

fail

p=none (_dmarc.airweb.fr)

Found

Record: v=DMARC1; p=none;
Found at: _dmarc.airweb.fr

Tag	Value	Meaning
v	DMARC1	Version
p	none	Policy

Checks

✗

Policy: none (monitoring only)

DMARC policy is set to 'none', which only monitors but doesn't protect against spoofing. Consider upgrading to 'quarantine' or ideally 'reject'.

#4
✓ Record published #5

DMARC record exists for this domain.
✓ Valid syntax #17

DMARC record syntax is valid.

No aggregate reports (rua)

DMARC record has no rua tag, so you receive no aggregate reports about who sends mail as your domain. Add rua=mailto:...

1024-bit DKIM key

1024-bit RSA keys are the minimum and are considered weak today: mail (1024 bits). Rotate to a 2048-bit key.

#23
✓ No problematic flags #24

No keys in test mode, revoked, or limited to SHA-1.

Hosts without IPv6

The following MX hosts could not be resolved to IPv6 addresses: magento.airweb.fr

#11
✓ Redundant MX hosts #12

Found 5 MX records, which provides redundancy for email delivery.
✓ At most 5 MX records #13

Found 5 MX records, which is within the recommended range (1-5).
✓ No localhost targets #14

No MX records pointing to localhost found.

Hosts are CNAMEs

MX records must point to a host name with A/AAAA records, not to a CNAME: mx1.airweb.fr -> aspmx.l.google.com

#22
✓ Reverse DNS confirmed #30

All 9 MX addresss have a PTR record that resolves back to them.

TLS

warn

no MTA-STS · no TLS-RPT · DANE on 0 of 5 MX hosts

Found

DANE (TLSA records)

MX host	TLSA	DNSSEC
aspmx.l.google.com	none	-
mx1.airweb.fr	none	-
alt1.aspmx.l.google.com	none	-
alt2.aspmx.l.google.com	none	-
magento.airweb.fr	none	-

Checks

!

Not configured

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
i

Not configured

TLS-RPT lets senders report TLS delivery problems to you. It is most useful together with MTA-STS or DANE.

#35
i

Not used

No MX host publishes TLSA records. DANE lets senders verify your mail server's certificate through DNSSEC; it requires DNSSEC on the MX host's zone.

#36

BIMI

info

No BIMI record

Checks

i

Not configured

BIMI shows your logo next to your mail in supporting mail clients. It requires DMARC enforcement.
