HOSTGRABER EXPERT GUIDE
Building an SPF policy that stays valid
SPF is evaluated against the envelope sender and sending IP. Each include, a, mx, exists or redirect mechanism can trigger DNS work, and the standard limits evaluation to ten DNS lookups. Oversized policies and multiple SPF records are common reasons legitimate messages fail authentication.
List every platform that sends as your domain—including business mail, website forms, billing systems and marketing services—then consolidate them into one record. Pair the finished policy with DKIM and DMARC so forwarded mail and visible From-domain alignment are handled correctly.

COMMON QUESTIONS
SPF Checker FAQ
Practical answers from the HostGraber team.
Can I publish more than one SPF record?+
No. Combine all senders into one policy to avoid PermError results.
What is the SPF 10-lookup limit?+
SPF evaluation permits at most ten DNS-triggering mechanisms. Exceeding it can make authentication fail.
Does SPF stop spoofing by itself?+
No. Pair SPF with DKIM and DMARC so receivers can check alignment and enforce a clear policy.
