 The SPF protocol is automatically integrated by Dialog Insight if you choose sub-domain delegation.

For more information, consult the checklist of basic configurations for your account. |
SPF (Sender Policy Framework) is a protocol that determines whether an email comes from a server authorized to use a particular domain name to deliver emails by comparing its IP address with a list of addresses published in the DNS of the domain of the SMTP envelope of the email.

The SMTP envelope is like the return address on a postal envelope: it is an address that is potentially different from the address indicated in the header of the letter contained in the envelope.
