Publish an SPF record
No sending service was detected, so this record says no server may send as samsungcloud.com. If you do send mail, add your provider's include before publishing.
samsungcloud.com
Some DNS providers want “@” here instead of the full domain.
v=spf1 -all
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.
- Add a new TXT record with the name and value above.
- 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?Mail relies on implicit A recordNeeds attention
- Warning: Mail relies on implicit A record
samsungcloud.com has no MX records, so senders fall back to its A/AAAA address (RFC 5321 implicit MX). Publish an explicit MX record, or a null MX ("0 .") if the domain should not receive mail.
SPFWho may send as you?No SPF recordFailing
- Fail: No SPF record
samsungcloud.com publishes no TXT record starting with "v=spf1", so receivers cannot tell which servers may send mail for it. Publish one SPF record listing every service that sends as samsungcloud.com.
How to fix this
DKIMAre your emails signed?No DKIM key found for the common selectorsNeeds attention
- Warning: No DKIM key found for the common selectors
None of the 47 selectors probed under samsungcloud.com publish a DKIM key. DNS cannot list selectors, so a key under a custom selector may exist: find the s= value in the DKIM-Signature header of a message you sent and check that selector. If DKIM is not set up, enable it at each service that sends mail for samsungcloud.com.
DMARCWhat happens to fakes?DMARC policy applies to only 50% of mailNeeds attention
- Warning: DMARC policy applies to only 50% of mail
pct=50 means the remaining 50% of failing mail is treated one step more leniently. Raise pct to 100 when you are confident.
How to fix this - Warning: External DMARC report address is not authorized
Reports go to samsung.com, which is outside samsungcloud.com. RFC 7489 requires that domain to publish a valid v=DMARC1 TXT record at samsungcloud.com._report._dmarc.samsung.com; without it receivers will not send you aggregate reports. Your report provider normally publishes this for you.
- Info: DMARC policy is quarantine; consider reject
Failing mail goes to spam rather than being refused. When reports show no legitimate failures, reject gives the strongest protection.

AlignmentDoes it match your From?No issues foundPass
Nothing to report.
BIMICan inboxes show your logo?No BIMI recordInfo
- Info: No BIMI record
No BIMI record at default._bimi.samsungcloud.com. 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.samsungcloud.com. MTA-STS (RFC 8461) makes sending servers require TLS and a valid certificate when delivering to you, which blocks downgrade attacks.
TLS-RPTWill you hear about failures?No TLS-RPT recordInfo
- Info: No TLS-RPT record
No TLS reporting record at _smtp._tls.samsungcloud.com. TLS-RPT (RFC 8460) tells senders where to send daily reports about failed encrypted deliveries to you.

Strengthen the DMARC policyTXT
Quarantines all mail that fails DMARC. Move on to reject once the reports stay clean.
_dmarc.samsungcloud.com
Some DNS providers want just “_dmarc” here.
v=DMARC1; p=quarantine; rua=mailto:scloud.ops@samsung.com; adkim=r; aspf=r
v=DMARC1;p=quarantine;pct=50;rua=mailto:scloud.ops@samsung.com;ruf=mailto:scloud.ops@samsung.com;aspf=r
Set up a TLS report addressinstruction
Sending servers will report TLS failures when delivering to samsungcloud.com, 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.samsungcloud.com
- Pick an address that will receive TLS reports: a mailbox you read (for example tls-reports@samsungcloud.com, created first) or a TLS reporting service. 2. Publish a TXT record at _smtp._tls.samsungcloud.com 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.samsungcloud.com
- 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://samsungcloud.com/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.samsungcloud.com with v=BIMI1, l= set to the logo URL and a= set to the certificate URL.
