Prevention of spam on the email server

Since the birth of the Internet, spam has accompanied each other. Especially with the popularity of online shopping, spam has become increasingly popular, anti-Spam is a waste of time on users' mailbox capacity, leading to property loss. Therefore, anti-spam has always been one of the top priorities of email system service providers, it is also one of the indicators to determine whether an email server is good enough.

China has always been the "hardest hit" of spam, but this situation has improved in recent years. According to Xinhua News Agency, the China Internet Association announced in Beijing on September August 25, the proportion of spam mails received by Internet users in China dropped from 2006 in early 63.97% to 2014 in the first quarter of 38.2%; china ranks second in 2006 to fifth in the percentage of globally occupied mails. I have to say that many Mail System Service Providers in China have made great contributions to this achievement. The well-known brand U-mail system is one of them. In view of the huge dangers of spam, I specially asked engineers U-mail Li to provide useful suggestions:

To prevent spam, you must first understand what it is? Currently, there are roughly three types:

1. Ad mail:

Most of them attract and boost potential customers by sending a large amount of advertising information.

2. fraud and forgery

Fraud is performed by forging part of the activity address, forging the contact address, and impersonating a user's familiar contact identity.

3. Spam

The email contains a virus or other webpage links containing viruses. When a user opens the email or link, the account and password are stolen or sensitive information is leaked.

After finding the problem, you can remedy the problem. The following is a summary of the Methods:

1. Reduce account exposure

1. Many spam senders collect recipient addresses over the Internet. Users should try to avoid leaving email addresses on public occasions such as websites, forums, and post bars.

2. Do not use the company's enterprise email address for online account registration.

3. strengthen user account management (prevent simple passwords and prevent passwords from being leaked or cracked. As a result, emails are used for illegal mass spam)

4. Avoid logging in to your email account (such as Internet cafes and free WiFi hotspots) in public places)

Ii. Strengthen Account Management in the Mail System

1. Disable the public registration function of the email system. If you need to register an email, the email system must be reviewed by the Administrator to prevent malicious registration and send spam.

2. tips for registering a new email account: if you have no special requirements, you should use less accounts or do not use admin accounts. If you have a large number of users, you can add underscores, dots, and other symbols as nicknames (for example, [email protected]).

3. Enhance anti-spam setting: add anti-spam and anti-virus gateways if conditions permit.

4. Strengthen effective account management: restrict the permissions of some accounts for sending and receiving emails from the Internet; Establish monitoring rules. Once an account is stolen or encounters an exception, it is immediately prohibited to use it.

5. Check the server status regularly, install efficient anti-virus software, and delete unnecessary applications, services, and tool software.

3. Deliver the defense work to professional service providers

Some may ask: Where do I remember so many things that I should pay attention to? In case of carelessness or carelessness, isn't it dangerous to come? Is there a permanent solution? In fact, you can choose an email server with high security and stability, and hand over the defense work to it. The U-mail system is a medium leader. When your account password is simplified, it will remind you to change it forcibly. Its integrated anti-spam and anti-virus modules effectively intercept and filter over 99% of spam viruses from the source, and develop a unique "Hot Spot" patented technology. In addition, the Anti-Spam mechanism of U-mail adopts the comprehensive scoring technology to filter and detect spam. You can also set custom rules and combine hundreds of custom rules to effectively filter out special sensitive emails.

4. Prepare for timely remedial measures

If you are not afraid of 10 thousand, what should you do in case of spam that causes paralysis of the email server? Timely remediation and good after-sales service are very important.
