This method is effective in dealing with existing spam, but as the saying goes, how can spam sit down? If the winweb technology is applied, I can easily create a plug-in that automatically performs mathematical problems to enhance the function of the mail server. After all, the questions on your mail server cannot be too complex, otherwise, the sender will not be able to do anything even if it is a real person.
In fact, the solution is to verify the sender's credibility. The sender cannot correctly verify its credibility without providing credible evidence. The 100% security solution is to accept only those emails from the contact list. For those business mailboxes, a better way is to set the mail template. Business partners can only send emails that meet the template.
Winwebmail server, a mail system provider on windows in China, provides the latest anti-spam mode that can eliminate spam by 100%, it tries to solve the spam problem that has plagued the Internet for many years by asking the sender to answer random mathematical questions.
The working principle of the mathematical model can eliminate spam by 100%:
1. when a mail address is a stranger to my mailbox, the mail system will first save it to my bin, and then automatically return a letter to the stranger's mail address, ask the sender to answer a random MATHEMATICAL question.
2. After receiving the correct mathematical answer from the recipient, the email system will move the original email from the bin to my inbox.
Q: Do anyone who writes to me need to calculate a math?
A: No.
All the addresses in my address book and all the addresses I used to write (reply) will directly enter the inbox without answering any math questions.
Case 1: if a friend writes to me for the first time, his email will be saved in a garbage bin first. After he sends the correct answer to the math question, the email will be transferred to my inbox. I replied to his email, and then we can keep in touch, and he no longer needs to do any math problems.
Case 2: I saved the address of this friend to the address book first, so he does not even need to know the problem of mathematics, so we can contact each other by email.
Case 3: I already have the address of this friend. write and say hello to him first, and then we can contact you via email. Of course, he does not know that there is a math problem.
Q: What should I do if the recipient does not answer a math question and this email will be placed in my bin, but the POP3 client cannot receive emails from the bin?
A: The latest version of winwebmail has integrated the bin mail data statistics function, that is, the POP3 client. You can also learn about and process emails in the bin in time.
Q: Will the spammers generate more spam mails by collecting the from addresses of these mathematical questions?
A: No.
Because the account used to send a mathematical question email is randomly generated by the system.
Q: Normally, the spam Sending address is invalid, but does it cause many bounce messages that fail to be delivered due to a mathematical problem?
A: No.
The Mail System intelligently processes such emails to avoid the troubles caused by "failed delivery.
Q: will it lead to an endless loop if the recipient has an automatic reply or requires a math verification?
A: No.
Because the winwebmail mail system has already considered the impact of many complex factors at the beginning of its design, and has been given priority in the design.
Q: Does the mathematical model increase the server traffic and load?
A: There will be a slight increase.
The number of math emails is very small, even if the network traffic caused by a complete statistical email is less than 1kb.
