didn"t the email protocol of a long time ago allow recipients to set more than one? Or is there any other reason why the mail system has to design an extra redundant function?

is not redundant, it is a necessary classification. The recipient is the direct target, which generally refers to the person directly related to this email, such as the executor of the task. CC means notification, notification, and the recipient is not directly related, but you need to know the content of the email, such as the leader in charge or other relevant people.
The advantage ofclassification is that the person who receives the email immediately knows what he or she should do with the email. If it is the recipient, you should read it and deal with it as soon as possible. If it is a CC, you usually do not need to read and process it right away. You can read it when you are free.
paste the email sending process found at your fingertips:
1QQSMTP,25 //2,
2:
"From:<@.com>\r\n" //()
"To:<@.com>\r\n"; //()
"Subject:\r\n\r\n" //
"" //

4STARTTLSTLS
5AUTH LOGIN

7MAIL FROM,QQ.
8RCPT TO
9DATA
10,\r\n.\r\n
11QUIT you can see that the email address is the one in TO, and the rest of the information, including CC, is actually at the end of the content.
in addition, in daily work, receiving mail is generally regarded as the party directly related to / responsible for the content of E-mail, and CC as the informing party, is also equivalent to a consensus, which is easy to be messed up?
