2. Cause of error

Because in the mail sent, the login user and the sender must be consistent, and in the test I logged in the user's mailbox is 163 mailbox, the sender's mailbox is QQ mailbox, resulting in error

3. Solutions

Ensure that the login mailbox is consistent with the sender's mailbox, either using 163 mailbox, or using QQ mailbox
