Customer Background:

As a well-known domestic higher education institution, a certain 985 university has high-quality teacher and student resources and rich teaching experience. They actively carry out cooperation and exchanges with foreign universities, organize teachers and students to participate in overseas exchanges and academic visits, and carry out in-depth cooperation in cross-border scientific research collaboration and talent cultivation, promoting the development of international education.


Email, as the main carrier of cross-border Internet communication, plays a critical role in academic exchanges. However, the process of overseas postal services is complex. The education industry holds sensitive information such as scientific research projects, teaching data, and teacher and student information, making it a key target for hacker attacks. Overseas postal services face significant challenges and difficulties!


Product Used:

Security Overseas Relay (Overseas Forwarding + Secure Overseas Receiving)


Analysis of Pain Points in Overseas Postal Services Industry:


1. Severe proliferation of spam emails: Abnormal email communication leads to low work efficiency.

According to the ';Enterprise Email Security Research Report for Q1 2023';, the education industry received 159 million spam emails (62% of the total) in the TOP100 domain received spam email sources, placing it at a high position. The education industry is still a major target for spam emails.


Customer Pain Points:

';Our email system receives a large number of spam and phishing emails from overseas on a daily basis. Not only do they take up mailbox space, but they also bring security risks and affect the timely delivery of normal emails, reducing the efficiency of academic exchanges.';

2. IP on the RBL List: Frequent email bounce backs from overseas.

Being listed on the RBL blacklist means that the server's IP address has been misused or spammed, thus damaging its credibility. In this case, emails sent from the server are likely to be marked as spam or rejected, further reducing email deliverability.


Client Pain Points:

';The education industry has long been engaged in frequent email exchanges with a large number of overseas journals, scientific research institutions and others, which is prone to triggering ordinary email systems to misjudge spam and causing false positives or message rejection, thereby obstructing normal exchanges and impacting the progress of academic communication.';

Coremail Secure Overseas Relay:

Provides a secure and reliable overseas postal service solution.


Coremail Secure Overseas Relay has two main modes: overseas forwarding and secure overseas receiving, which are suitable for different email send and receive scenarios, providing a secure, reliable, and efficient solution for international exchanges and information sharing in the education industry.


1. Intelligent DNS ensures the quality of overseas email delivery.

During the delivery of emails to overseas recipients, the system first performs CAC anti-spam detection and channel intelligent analysis based on the user's email content, sender domain, and recipient domain, and selects the best and highest quality channel to deliver the email. In the event of poor network communication, GFW interception, or RBL, the system can make multiple attempts to deliver the email and ensure the quality of the proxy IP used for delivery, thereby increasing the success rate of overseas email delivery and reducing delivery latency.


2. Global relay node IP monitoring reduces the impact of RBL.

When a proxy IP is tagged on the RBL, the system automatically selects a reserve proxy IP with good reputation for switching, greatly reducing the impact of RBL on overseas delivery and ensuring the delivery performance of each relay node to increase email deliverability.


3. Cloud isolation to avoid security attacks on the email system.

Secure overseas receiving has a multi-dimensional and multi-level email detection mechanism, and supports automatic updating of spam feature libraries. It can comprehensively, intelligently, efficiently, and instantly identify and intercept the latest spam emails to ensure the security of received overseas emails. Administrators can also manage suspicious spam emails that enter the isolation zone, including queries, deliveries, downloads, deletions, and other operations, to retrieve messages that have been incorrectly intercepted. Users can also use the isolation reminder email to retrieve their email themselves.


Client Feedback:

';Before using Coremail Secure Overseas Relay, there was a lack of buffer for the delivery or interception of overseas emails, which could result in lost or incorrectly intercepted emails. Since upgrading to Coremail Secure Overseas Relay, the CAC has effectively improved the recognition rate of spam emails and placed suspicious emails in an isolation zone, where faculty and students can retrieve their required emails, reducing the inconvenience caused by false positives or message rejection. For the operations and maintenance personnel, it greatly improves the efficiency of disposing of overseas email issues. I would give this product an 8 out of 10. In the future, I hope to see improved user settings and access to further enhance the product of Coremail Secure Overseas Relay.';
