Leanote使用邮件服务器异常

笔者在搭建docker版leanote过程中，发现邮件服务器异常，按照下述修改以后，即可解决该问题

//leanote/app/service/EmailService.go原有代码
+111 auth := smtp.PlainAuth("", username, password, hp[0])

//应根据阿里云示例中描述，采用go发送smtp发送邮件的时候需要增加代码段
type loginAuth struct {
    username, password string
}
func LoginAuth(username, password string) smtp.Auth {
    return &loginAuth{username, password}
}
func (a *loginAuth) Start(server *smtp.ServerInfo) (string, []byte, error) {
    // return "LOGIN", []byte{}, nil
    return "LOGIN", []byte(a.username), nil
}
func (a *loginAuth) Next(fromServer []byte, more bool) ([]byte, error) {
    if more {
        switch string(fromServer) {
        case "Username:":
            return []byte(a.username), nil
        case "Password:":
            return []byte(a.password), nil
        }
    }
    return nil, nil
}
