DKIM email security also ensures that the message comes from the appropriate mail server or IP address, but it also offers additional security layers. Similar to SPF, DKIM is a DNS TXT record. If the receiving mail server detects that the sender does not match the SPF record, it may be blocked. SPF exists in the form of a Domain Name Service (DNS) text (TXT) record which identifies precisely which mail servers and IP addresses are allowed to send email from a specific domain. In other words, it is about making sure the email is actually coming from who it says it is coming from. SPF is an email security open standard framework designed to prevent sender address forgery. Without knowing how these tools work, senders could inadvertently run afoul of the protocols and find that their messages are not getting through. But a solid grasp of the processes and technology behind email security protocols is also critical for email senders. They help to weed out spam, phishing scams, and other potentially damaging messages. Proper implementation of these protections is, of course, essential for recipients. Understanding these email security standards is critical for both email receivers and senders. SPF, DKIM, and DMARC were explicitly designed to reduce spam and other possibly unsafe messages. If sending and receiving email is a central part of your business strategy, it is essential to understand the protocols that have been developed to keep it safe.
