//
// PS_01: 成败的判断关键在此一句, 如果连接服务器失败, 都会在控制台输出相应失败原因的 log,
// 仔细查看失败原因, 有些邮箱服务器会返回错误码或查看错误类型的链接, 根据给出的错误
// 类型到对应邮件服务器的帮助网站上查看具体失败原因。
//
// PS_02: 连接失败的原因通常为以下几点, 仔细检查代码:
// (1) 邮箱没有开启 SMTP 服务;
// (2) 邮箱密码错误, 例如某些邮箱开启了独立密码;
// (3) 邮箱服务器要求必须要使用 SSL 安全连接;
// (4) 请求过于频繁或其他原因, 被邮件服务器拒绝服务;
// (5) 如果以上几点都确定无误, 到邮件服务器网站查找帮助。
//
// PS_03: 仔细看log, 认真看log, 看懂log, 错误原因都在log已说明。
