SPF (Sender Policy Framework) is an email authentication mechanism that helps verify whether a message was sent from a server authorized to send email on behalf of a specific domain.<\/p>\n\n\n\n

SPF works through a DNS record published by the domain owner. This record contains a list of IP addresses and mail servers that are permitted to send messages for that domain.<\/p>\n\n\n\n<\/div>\n\n

When an email is received, the receiving mail server compares the sending server’s IP address with the SPF record published in the sender’s DNS zone. If the sending server is not listed as authorized, the message may be marked as suspicious, classified as spam, or rejected entirely.<\/p>\n\n\n\n
