Which of the following services checks whether the sender's IP address is associated with the sender’s domain name when receiving email?
The correct service for checking whether the sender's IP address is associated with the sender’s domain name when receiving email is SPF. SPF (Sender Policy Framework) allows domain owners to specify which IP addresses are permitted to send email on behalf of their domain. When an email is received, the recipient's mail server checks the SPF record of the sender's domain to verify if the email is being sent from an authorized IP address. This helps in preventing email spoofing and ensures that the email is legitimate.
The correct answer is: C. SPF Here's why: SPF (Sender Policy Framework) allows domain owners to specify a list of authorized IP addresses that can send email for their domain. When an email is received, the receiving mail server checks the SPF record of the sender's domain to see if the IP address used is authorized. If it's not, the receiving mail server can reject the email or mark it as spam.
The correct answer is A. DKIM (DomainKeys Identified Mail). DKIM is a service that checks whether the sender's IP address is associated with the sender's domain name when receiving email ¹. DKIM is a way to prevent email fraud by authenticating the domain name from which a mail was sent and making sure it was not sent from a different domain ².
