Qq mailbox received an inexplicable email from Korea.

Those are mass emails, that is, posting indiscriminately, and many people they don't know! Just like mobile phones sometimes receive text messages from people they don't know, those files may all be viruses. Will steal q, if found, just delete the front. Just don't open the file.

Those are mass emails, that is, posting indiscriminately, and many people they don't know! Just like mobile phones sometimes receive many text messages from strangers.

Check whether the senders are normal, and if so, stop them.

If there is no law at all, it can't be banned, and it's useless to report it. Because email settings are rejected according to the rules, there is no way for the program to stop irregular spam!
