Fix this firstThe change with the biggest effect

Strengthen the DMARC policy

Quarantines 25% of mail that fails DMARC, a safe first step: check the reports for legitimate senders that fail before going further.

TypeTXT

Name / Host

_dmarc.fundamenta.gr

Some DNS providers want just “_dmarc” here.

Value

v=DMARC1; p=quarantine; pct=25; rua=mailto:postmaster@fundamenta.gr; adkim=r; aspf=r

Replaces

v=DMARC1;p=none;rua=mailto:postmaster@fundamenta.gr;ruf=mailto:postmaster@fundamenta.gr;

How to apply it

Sign in where your domain’s DNS is managed. This is often where you bought the domain, such as Cloudflare, GoDaddy or Namecheap.
Find the existing TXT record with that name and replace its value.
Save, then come back and re-check. DNS changes can take up to a few hours to show.

All checks

MXCan servers find your inbox?Only one MX hostInfo

Info: Only one MX host
All mail for fundamenta.gr goes to smtp.google.com. Most hosted providers make that one name highly available; if you run your own server, consider a backup MX.

SPFWho may send as you?SPF ends in softfail (~all)Info

Info: SPF ends in softfail (~all)
"~all" is common and works well with DMARC. "-all" is stricter; switch when you are sure every sender is listed.

DKIMAre your emails signed?DKIM key publishedPass

Pass: DKIM key published
fundamenta.gr publishes a DKIM key under google.

DMARCWhat happens to fakes?DMARC policy is noneNeeds attention

Warning: DMARC policy is none
A none policy only monitors: mail that fails DMARC is still delivered, so anyone can spoof the domain. Once reports show your legitimate senders pass, move to quarantine and then reject.

Nothing to report.

BIMICan inboxes show your logo?No BIMI recordInfo

Info: No BIMI record
No BIMI record at default._bimi.fundamenta.gr. BIMI is optional: it shows your logo next to your mail in supporting inboxes once DMARC is enforced.
How to fix this

MTA-STSIs mail to you encrypted?No MTA-STS recordInfo

Info: No MTA-STS record
No MTA-STS record at _mta-sts.fundamenta.gr. MTA-STS (RFC 8461) makes sending servers require TLS and a valid certificate when delivering to you, which blocks downgrade attacks.
How to fix this

TLS-RPTWill you hear about failures?No TLS-RPT recordInfo

Info: No TLS-RPT record
No TLS reporting record at _smtp._tls.fundamenta.gr. TLS-RPT (RFC 8460) tells senders where to send daily reports about failed encrypted deliveries to you.

Other fixes

Publish the MTA-STS recordTXT

Tells sending servers that fundamenta.gr publishes an MTA-STS policy at https://mta-sts.fundamenta.gr/.well-known/mta-sts.txt. Change the id whenever the policy file changes.

TypeTXT

Name / Host

_mta-sts.fundamenta.gr

Some DNS providers want just “_mta-sts” here.

Value

v=STSv1; id=202610021423

Host the MTA-STS policy filepolicy-file

Serve this file over HTTPS with a valid certificate for mta-sts.fundamenta.gr. It lists your MX hosts and starts in testing mode; switch to mode: enforce once TLS-RPT reports show no failures.

Set up a TLS report addressinstruction

Sending servers will report TLS failures when delivering to fundamenta.gr, which you need before enforcing MTA-STS. The address must accept TLS reports; a DMARC report address does not necessarily do so.

Applies to: _smtp._tls.fundamenta.gr

Pick an address that will receive TLS reports: a mailbox you read (for example tls-reports@fundamenta.gr, created first) or a TLS reporting service. 2. Publish a TXT record at _smtp._tls.fundamenta.gr with the value v=TLSRPTv1; rua=mailto:<that address>.

Prepare BIMIinstruction

BIMI shows your logo next to messages in supporting inboxes, but only for mail that passes DMARC under an enforced policy.

Applies to: default._bimi.fundamenta.gr

Enforce DMARC first: p=quarantine or p=reject at 100% (no pct below 100). 2. Convert your logo to an SVG Tiny PS file and host it over HTTPS, for example https://fundamenta.gr/bimi/logo.svg. 3. For Gmail and Apple Mail, obtain a VMC or CMC certificate for the logo. 4. Publish a TXT record at default._bimi.fundamenta.gr with v=BIMI1, l= set to the logo URL and a= set to the certificate URL.
