SPF has potential benefits beyond helping to identify spam. In particular, if a sender offers SPF information, then recipients can use the SPF “PASS” results in combination with a whitelist to identify known trustworthy senders. Some scenarios, such as compromised systems and shared email senders, limit these uses.
The Simple Mail Transfer Protocol allows any computer to send e-mail pretending to come from any specific address. This is exploited by spammers , who frequently use spoofed e-mail addresses , which makes it harder to trace the origin of a message, and easier for spammers to hide their identities and thus avoid liability. It is also used in phishing techniques , where users can be tricked into revealing private information in response to an e-mail supposedly sent by an organization, such as a bank.
