e-mail based on Java mail to achieve a simple QQ mailbox

Just learn Java mail-related knowledge, first write down this blog, easy to read the study later.

-----------------------------The first step to turn on the SMTP service

Open the SMTP service in the account set up in the QQ mailbox

Complete validation

Get the Authorization code (used when the code is implemented later)

-----------------------------Second Step environment configuration

Download third-party libraries

Https://github.com/javaee/javamail/releases

-----------------------------The third step of code implementation

-----------------------------Fourth Step effect show

-----------------------------The fifth step recommended
