If an SPF record is misconfigured, it can cause email delivery issues. Email servers use SPF records to determine whether an incoming email is from a legitimate source or not. If the SPF record is incorrect or incomplete, the recipient’s email server may reject the email or mark it as spam. This can result in the sender’s email server being blacklisted, which can impact the delivery of future emails. Additionally, a misconfigured SPF record can leave a domain vulnerable to email spoofing, which can lead to phishing attacks and other security breaches.
