College Mail server Building scheme

Solution:

First, high security

The U-mail mail system provides military-grade security protection, in several ways:

1. Eliminate spam and viruses: u-mail embedded Kaspersky Antivirus engine (real-time updates, free upgrades), comprehensive use of "hotspot" patented technology, black \ White list, Ayesian heuristic, "Outbreak protection", Bayesian algorithm, fourth generation of anti-spam engine based on behavioral recognition, gray list, SPF CHINESE_CF, enterprise domain spam score and other international advanced anti-spam technology, build three-dimensional, deep, multi-level defense system.

2. The whole process of mail transmission encryption Protection: The whole process of encrypting the message, using SSL encryption, PGP encryption, SMTP message encryption (TLS encryption) and other encryption technology to ensure information security.

3. Guard against Spy: U-mail mail system will be forced to filter out the password set simple user, force it to modify, restrict some users can only log in fixed IP segment, prevent access from some host, region, IP segment, turn on Spf/sender-id and Backscatter protection, sender verification To prevent forged messages.

4. Restrict user rights: Establish corresponding domain according to the system, double audit mechanism to ensure that the message will not disclose confidential, restrict the outgoing permission of some accounts, can realize the full monitoring of sending and receiving mail.

Second, ultra-strong stability

1.u-mail High-performance caching mechanism to ensure the stability of large-scale concurrent access to users, the perfect queue mechanism to ensure the reliability of the delivery of the user's letter in the case of large traffic flow, the daily sending quantity reaches tens of millions of seal levels; Automatically monitors service module failures, alarms, and attempts to recover automatically.

2. Dual-Machine hot standby technology: When one server fails, the service task is assumed by another server, so that the system can provide the service continuously without the need of manual intervention.

Third, participate in management, ensure efficient office

2. Many office platforms can be centralized to a Web page, to "Single sign-on"; U-mail mail system and Foxmail, ERP, OA system and other office platforms seamlessly docking, providing a rich API interface, with good extensibility.

3. Most operations can be done on Web pages, and data migration is simple and convenient.

4. Faculty and students can use laptops, tablets, mobile phones and other equipment anytime, anywhere to receive, processing mail, and immediate arrival, to ensure smooth communications, the majority of teachers and students coordinated action, stronger cohesion.
