SPF Lookup Limits

Sender Policy Framework (SPF) defines a limit of only 10 DNS lookups that may be initiated while evaluating a domains SPF record.  This limit is quickly breached given increased dependencies on SaaS platforms and third-parties sending email on behalf of an organization’s domain.  Exceeding the SPF Lookup limit causes authentication errors at the email receiver and increases risks associated with fraudulent email spoofing.  Our state of the art platform solves the SPF lookup limit in a unique way that allows support for a virtually unlimited number of authorized senders while providing near-real-time-global visibility into emails sent  on behalf-of your domain.
