Have you heard of Sender Policy Framework (SPF)?
The above situation occurs when the Sender Policy Framework (SPF) is not active on your server. SPF is an identification system that prevents other domains from sending emails to your audience, preventing them from receiving inconvenient emails on your company's behalf.

This protocol works as follows:

The system checks whether the emails were sent by the same server contracted by your company, preventing your audience from receiving these types of unauthorized emails that have nothing to do with your service.
When an email is received, the program checks whether the server sending it is authorized to use the domain. If it is not, the message is immediately rejected.


How does the SPF perform this function?
The protocol is configured according to your domain's DNS table, with a TXT entry, which informs which servers are authorized to send emails on behalf of your company.

As previously mentioned, if the sender is not informed, the email will be rejected, ensuring the safety of your audience and employees.

There are four attributes of the SPF record to program this system:

+Pass: Indicates that the IP address is authorized to send messages from the domain.
Fail: Indicates that the IP address is not authorized to send messages on behalf of the domain.
SoftFail: In this case, the domain may or may not authorize the IP address, i.e., the message is not discarded immediately, but waits to be subjected to other tests.
Neutral: This attribute is equivalent to having no SPF. The domain owner can decide whether the server will be allowed to send messages or not.


How to configure SPF?
The first step to defend against this threat is to publish information from an SPF record in the DNS zone of the domain .

This way, when a message arrives from another server claiming to be from this domain, the information will be recorded there and it will be possible to know whether it is a forgery or whether it complies with the SPF record.
