问题描述
我有可以正常工作的SMTP解析器.从第三方软件接收流量时出现问题，该软件发送双换行符为"\ r \ n \ r"(不包含第二个"\ n").当前，此类连接被终止为不兼容的SMTP.有人可以解释一下RFC关于这种有趣的"双换行符的确切含义吗?我可以假设发送这样的数据的软件确实做错了吗?
I have SMTP parser that works mostly fine. There is a problem when receiving traffic from third party software that sends double newlines as "\r\n\r" (without the second "\n"). Currently such connections are terminated as non-compliant SMTP. Can somebody explain what exactly RFC says about such "funny" double newlines? Can I asume that software that sends data like that is doing something really wrong?
