SPF Checker
Enter SPF check parameters. [ Show/hide more parameters ]
What Is This?
Use the SPF Checker to simulate the SPF evaluation for an email specified by the parameters.
Which SPF Versions Are Supported?
The only supported version is SPF Classic (the draft version published in May 2004). Get this SPF draft version here.
What Is the Purpose of the "HELO/EHLO domain" Parameter?
SPF evaluation falls back to the HELO/EHLO command argument domain if the email checked has a blank (NULL) envelope sender address (e.g. Delivery Status Notifications). Also the HELO/EHLO domain may be used during macro expansion.
What Is the Purpose of the "SPF record data" Parameter?
Use this field to test an SPF policy which has not been published yet. The contents of this field override the domain information (i.e. the checker will not look up the domain's SPF policy), so you can enter a custom policy here. This can come handy also when you have a problem with your SPF policy record.
What Are the Limitations of the SPF Checker?
The maximum check time is 30 seconds and the maximum recursion level is 10.
I Have Updated My SPF Policy, but the Checker Uses the Old Version - Why?
SPF policies are published via DNS and they may be cached according to the DNS caching rules. You may have to wait a little before the previous version gets out of the cache.
Which SPF Library is Used By This Validator?
The library behind this validator is our own SPF library developed for ORF.
