DOMAIN HEALTH
notion.so
4 ISSUES
0 critical
SPF
v=spf1 ~all
DKIM
Probed 38 selectors, none found
DMARC
p=quarantine pct=100
MX
no MX records
BIMI
VMC present
MTA-STS
not published
We could not find a published DKIM key under any common selector. Modern receivers (Gmail, Outlook, Apple) weight DKIM heavily.
FIX
Configure DKIM signing on your domain and publish the public key as a TXT record at <selector>._domainkey.<your-domain>.
Your domain has no MX records. Inbound mail will fail. (This is fine if the domain is send-only or doesn't receive mail at all — but in that case prefer a null MX, see fix.)
FIX
If this domain receives mail, configure MX records pointing to your mail provider. If it never receives mail, publish a null MX ("0 .") to explicitly signal that.
Your SPF policy is ~all. Because your DMARC policy is at enforcement, DMARC already acts on alignment failures regardless of the SPF qualifier, so this is informational. Tighten to -all once your sources are confirmed.
FIX
Once you are confident your SPF is correct, harden the policy to -all (hard fail).
MTA-STS protects against downgrade attacks during SMTP delivery. Recommended for serious senders.
FIX
Publish an MTA-STS policy at mta-sts.<your-domain> and a TXT record at _mta-sts.<your-domain>.
