Finding: No SPF Record
This finding means your domain publishes no SPF record at all. Receiving mail servers have no way to tell which servers are allowed to send email as your domain, so anyone can send mail that appears to come from your addresses.

What it means
SPF (Sender Policy Framework) is a TXT record that lists which servers are authorized to send email for a domain. Nivaronix looked up your domain's TXT records and found none beginning with v=spf1 — no SPF record has been published at all.
Why it matters
Without an SPF record, receiving mail servers that check SPF have nothing to check against, so they cannot reject mail sent from unauthorized servers on that basis. This is how domain spoofing usually starts — attackers send mail that appears to be from you, which is the classic opening move in invoice fraud, payroll fraud, and phishing campaigns that borrow your brand's trust. This finding is separate from the one Nivaronix reports when an SPF record exists but is set to a strong policy — see SPF Record Enforces a Hard Fail for what that end state looks like.
What Nivaronix checks
Nivaronix performs a live TXT lookup on your domain and isolates any record beginning with v=spf1. This finding fires when the lookup completes but no such record is found.

How to fix it
- List every service that sends email on behalf of this domain — your mail provider, helpdesk, marketing platform, invoicing tool, and anything else.
- At your DNS host, add a TXT record starting with
v=spf1and aninclude:mechanism for each of those services. - End the record with
-allso receivers reject mail from any server not listed.
v=spf1 include:<your-mail-provider> -all
How to verify the fix
Re-run the SPF & DMARC checker and confirm it now reports exactly one SPF record ending in -all.
