DMARC is a technical specifications created and implemented in order to reduce the frequency, as well as the very potential, for email abuse. The term itself stands for "Domain-based Message Authentication, Reporting, and Conformance". The process is implemented using a standardize system of protocols which is specifically designed to reduce and ultimately end email abuse issues.
DMARC works by standardizing the process of how email users perform their email authentication. Ultimately, this means that people who send regular emails will be able to receive constant authentication results for all of the messages they send via well-known email services such as Gmail, Hotmail, Yahoo, AOL and others who use the system.
The ultimate idea is of course to encourage regular email users to make frequent use of DMARC phishing prevention service to send authenticate emails. Over the long term, this will mean that it will become more and more difficult for fraud and identity theft to occur via the medium of email. The less fraud that is possible, the more reliable the medium of email will become.
The email user who is in possession of this system is protected from such issues as email fraud and identity theft precisely because the system has been adopted by all of the major email providers. Therefore, he or she has a measure of protection that is standardized and recognized all over the world.
Using the DMARC email security allows the email sender always has an instant and reliable indication that the email they have just sent is fully protected by SPF and DKIM protection protocols. This indication will immediately inform the receiver of this email if either or both of these protection protocols have failed. The receiver of this faulty or fraudulent email will then have a choice of what to do with this message, such as report it, refuse to receive it or simply trash it altogether.
Perhaps the most beneficial aspect of this excellent new email protection system is that it removes all of the speculation and "guess work" from the handling of these failed or fraudulent emails. This limits the receiver's exposure to emails which may contain malware, worms, or virus codes. It also gives the receiver of these bad messages a way to report back to the original sender that the security of their email system has been badly compromised.
Of all the ingenious methods of online protection that have been come up with over the course of the past decade, this system has to rank as one of the most important. Millions of emails are sent each day. DMARC email security is thus a permanent matter of safety, and this system is well worth getting to know.
