Security measures are in place

[subornaakter20]

Most spam and phishing emails are sent as "spoofed emails" that misrepresent the sender. Because they are sent pretending to be from a company or a third party, there have been many cases where personal information such as login IDs, passwords, and credit card numbers have been stolen without the recipient realizing that the email is a spoofed email, which has become a major problem in recent years.

That's why the technology of "sender leads for commercial real estate authentication" was developed. Sender authentication is a technology to confirm whether an email was delivered from a legitimate sender. The main sender authentication methods are "SPF" and "DKIM".

"SPF" determines whether an email was sent from a legitimate domain (sender) based on the IP address, which is the Internet address. On the other hand, "DKIM" is a technology that determines whether an email was sent from a legitimate domain (sender) based on the digital signature.

Without such security measures, not only will spam be delivered, but even if an email is sent from a legitimate address that actually exists, it may be recognized as a spoofed email and the recipient may refuse to receive it, resulting in the email never being delivered. By using sending domain authentication, the sender can properly deliver the intended information to the recipient, and the recipient can prevent the damage caused by spam.
