Senders of incoming email are identified primarily through the email's header information, which includes the "From" field displaying the sender's email address. Additionally, email servers use various authentication protocols, such as SPF (Sender Policy Framework) and DKIM (DomainKeys Identified Mail), to verify that the email originates from an authorized server. This helps prevent spoofing and ensures the legitimacy of the sender. Furthermore, the sender's IP address can also be traced in the email headers for additional verification.
