[Case Study] A2 Corporation
Introducing a case where the previously unclear situation regarding spam email countermeasures has become understandable!
We would like to introduce a case study on the implementation of "DMARC/25" at A2 Corporation. The company had previously set up SPF records as a measure against spoofed emails, but they were unable to ascertain the actual number of spoofed emails that failed authentication. In order to confirm the status of their measures against spoofed emails, they chose our "DMARC/25," which offers complete support in Japanese, as many DMARC analysis services are foreign products. By implementing "DMARC/25," they were able to understand the status of SPF authentication and identify issues related to third-party signatures and email forwarding. This has been useful for their future measures against spoofed emails. [Challenges Before Implementation] ■ Although they believed that the SPF record settings should have mitigated spam emails with spoofed sender addresses, they did not know how many emails were actually failing authentication. *For more details, please refer to the PDF document or feel free to contact us.
