What this check does
Enter the domain used by your envelope sender or Return-Path. Deliverlens looks up its TXT records, identifies the SPF policy, and checks its structure, mechanisms, IP ranges, and ending qualifier.
How to read your result
The report tells you whether an SPF policy was found and highlights common problems such as multiple records, invalid terms, malformed networks, or overly broad authorization. It checks the domain policy; it does not recreate the SPF result for a specific received message.
What to do next
Confirm every service that is allowed to send for the domain before editing SPF. Keep one SPF record, follow each sender’s current instructions, publish the smallest safe change, and check the domain again.
Common questions
Why can SPF look correct while an email still fails?
The message may use another Return-Path domain, sending IP, or forwarding route. Compare the report with the authentication details from that message.
Can Deliverlens create the final SPF record for me?
The checker can identify problems, but the final policy depends on every service authorized to send for your domain.
