What if the mail is all garbled?

In fact, garbled emails are mainly caused by different coding methods adopted by senders and receivers. Now, in order to keep up with the world, most e-mail servers begin to adopt Unicode(UTF-8) encoding method, but some e-mail servers adopt other encoding methods, such as Yahoo. Com and Hotmail. Com, in which GB23 12 coding is still adopted, and some of them adopt BIG5 coding. When the servers with different encoding methods send emails to each other, there will be a garbled phenomenon when displaying the emails of the other party, and the contents sent by the other party will not be seen. Solution:

When sending and receiving e-mail, you can use special e-mail sending and receiving software such as outlook and faxmail. These softwares support multiple encoding methods, and you can customize which encoding method to use when sending and receiving emails.

There are many people who just like to send and receive emails on web pages and can't decide their own coding methods. When they receive garbled code, they can take the following methods to view the content:

First copy the garbled content, and then create a new text file on the desktop, such as [New Text Document. Txt], then open this file, paste the copied content and save it, and then rename the file as. Then double-click to open it. At this moment, you can still see the garbled code. You can click on IE- Coding-Unicode(UTF-8-8) or GB 2365438+ to view it. The following is a screenshot of the process.

A general term for letters and parcels delivered by post offices. Mail is divided into domestic mail and international mail. Domestic mail can be divided into letters and parcels according to the nature of content. In China, letters include letters, postcards, printed matter and books for the blind, and parcels include parcels and express parcels. International mail is divided into international letters and international parcels. The former includes letters, postcards, printed matter, books for the blind and small bags; The latter is divided into ordinary parcels, fragile parcels, insured parcels and oversized parcels. Mail can be divided into registered mail, express mail, airmail, insured mail and collected mail according to the procedures, delivery methods or delivery time limit. The post office issues a receipt at the time of receiving and posting, registers it at the time of handling, and asks the recipient to sign for it at the time of delivery, which is collectively called receipt mail.

The delivery order of mail is divided into four links: receiving and sending, sorting and sealing, and transportation and delivery. Receiving and mailing methods are mainly to set up mailboxes, mailboxes and direct receiving and mailing in the post office business window. Sorting and sealing is to separate the mail according to the sending place, and then seal the sorted mail into mail packages (bags, sets) for shipment. Transportation is the general contractor who transports the mail to the destination through the designated postal route. There are two delivery methods: address delivery and post office delivery. Undeliverable messages are usually returned to the sender. Undeliverable and unreturnable mails are dead letters, which are opened centrally by designated institutions. If clues can be found, they will be returned, and those that are not dead will be stored for a certain period of time and destroyed or otherwise disposed of.

1.TCP protocol is used for mail transmission between mail servers. Why is mail sometimes lost?

The SMTP protocol between mail servers uses TCP connection, which can ensure the accurate transmission of mail between mail servers. However, due to the failure of the mail server itself, such as insufficient mail space, the mail cannot be transmitted and will be lost.

2. Why does the sender's user agent not send the mail directly to the recipient's user agent, but transmit it through the mail server?

Due to the limitation of the user's computer performance, it is impossible to run programs to send and receive emails, and it is impossible to continuously run and connect to the Internet. Therefore, they can only temporarily store the letters in the mail server, and users can download them when needed.
