Authorizes which servers may send mail for the domain

SPF is published and within limits.

Policy: -all
DNS lookups: 3 / 10

Ends in -all (hardfail): unauthorized senders are rejected.
Uses 3 of 10 allowed DNS lookups.

v=spf1 mx ip4:212.210.177.214 ip4:109.69.200.11 ip4:217.169.111.37 ip4:109.69.200.35 ip4:217.169.111.241 ip4:20.101.119.142 include:spf.protection.outlook.com include:servers.mcsv.net -all

DKIM

Pass

Cryptographically signs outgoing mail (best-effort selector probe)

DKIM key published for 2 known selectors.

Selectors: selector1, selector2

Found a DKIM key at selector1._domainkey.fabbricadigitale.it
Found a DKIM key at selector2._domainkey.fabbricadigitale.it

DMARC

Warning

Tells receivers what to do with mail that fails SPF and DKIM

DMARC is published but not fully enforcing.

Policy: p=none
Coverage: 100%

Policy p=none: DMARC is in monitoring mode only and does not block spoofed mail.
No rua address: you receive no aggregate reports to monitor abuse.

v=DMARC1; p=none;

MTA-STS

Not set

Enforces TLS for inbound mail and prevents downgrade attacks

No MTA-STS policy. Inbound mail can be delivered without TLS.

TLS-RPT

Pass

Receives reports about TLS delivery failures

TLS reporting is configured.

Reports to: mailto:[email protected]

TLS delivery failure reports are being collected.

v=TLSRPTv1; rua=mailto:[email protected]

BIMI

Not set

Displays your verified brand logo in supporting inboxes

No BIMI record. No brand logo is published for inboxes.

Checks query live DNS over Cloudflare and the public MTA-STS policy endpoint. DKIM selectors cannot be listed from DNS, so DKIM detection probes common provider selectors only.
