Email spoofing is used in phishing attacks to trick users into believing the message is from a person or entity they either know or can trust.

Email spoofing is possible because the email system used to represent email addresses provides no way for outbound servers to verify the legitimacy of the sender's address.

Each open email message has a sender address that displays the address of the originating user's email application or service.

Recipients' email servers can flag your legitimate emails as spam and put them in the junk folder due to poor server reputation, drastically affecting your email deliverability.

Domain-Based Message Authentication, Reporting, and Conformance is an email authentication protocol that, when properly implemented, can dramatically minimize email spoofing, BEC, and impersonation attacks.

As your SPF record becomes invalid due to too many DNS lookups, your domain, in turn, becomes vulnerable to email spoofing attacks and BEC. Therefore, it is important to stay under the SPF limit of 10 lookups to ensure email deliverability.
