SPF Record Generator

Build one draft SPF record from the sending IPs and include domains you provide.

01 / INPUT

Prepare one policy—not a second SPF record.

STEP 01
Separate multiple addresses with commas or new lines.
Use only addresses you have explicitly authorized.
Enter include targets supplied by your senders, separated by commas or new lines.
This is an explicit draft choice; review all legitimate traffic before using -all.

Draft generation is local. It will not publish DNS or discover other senders.

Your entries stay in this tab. Not sent to or saved by Sky. Export or print before closing or reloading, or your entries will be lost. Do not include passwords, API keys, recipient lists or private logs.

NEXT / INTERPRET THE EVIDENCE

Use this result with the sending path, receiver response and authorized provider signals—not as a stand-alone placement verdict.
