1，从上面的错误信息可以得出，是因为授权问题造成不能正常连接到smtp服务器。。首先开启一定要记得把邮箱的pop3.smtp服务开启。。（如：在163邮箱里的设置进去SMTP/POP3/IMAP，开启SMTP/POP3/IMAP服务。。）

注：设置的‘授权密码’很可能和‘登录密码’不同。。

所以一定要分清。。

发送邮件需要用到三个第三方jar包：activation-1.1.jar/commons-email-1.1.jar/mail-1.4.jar

package selenium_utils;
    
    import org.apache.commons.mail.EmailException;
    import org.apache.commons.mail.SimpleEmail;
    
    public class SendEmail {
        public static void sendToEmail(String content) {
            SimpleEmail email = new SimpleEmail();
            email.setHostName("smtp.163.com");
            email.setAuthentication("邮箱名@163.com", "注意是‘授权密码");
            try {
                email.setFrom("邮箱名@163.com");
                email.addTo("要发送的邮箱名@xx.com");
                email.setSubject("selenium自动化测试邮件");
                //email.setContent("这是我们发送的测试邮件","text/html;charset=utf-8");
                email.setContent(content, "text/html;charset=utf-8");
                email.send();
            } catch (EmailException e) {
                e.printStackTrace();
                System.out.println(e);
            }
        }
    
        public static void main(String[] args) {
            sendToEmail("我们发着玩~~");
        }
    }
