The email name cannot be used during email sending.

Recently, the project was quite urgent. I couldn't finish working hours, so I had to work overtime. But after work, my Office was too busy and I had to go home to do it.
The project uses mail-related operations. Because SMTP is called by the company mail server in the company, there is no mail server at home, so we have to use the mailbox of 163 to send emails.
163 verification is required. Change the user name, password, and test. An error occurs immediately.
Email sending is not allowed
If you are depressed, change the user name for sending to the user name of 163. The problem is solved.
