qmail 日志中Remote_host_said的问题

netlogon

我查看我的qmail日志，有如下的信息：

从Remote_host_said:_250的代码可以看出，邮件是成功被投递了，但是Remote_host_said:_250后面显示的信息却不一样，例如:queued_as_7582A19407B,1255114812_qp_26840_by_abc.com,dirdel
请问，这些信息分别是什么意思呢？
是不是对方不同的邮件系统，返回的250信息不一样呢？
谢谢

250是回应码，是给程序看的。

queued_as_7582A19407B,1255114812_qp_26840_by_abc.com,dirdel
为回应语，是给人看的


回应码含义是要遵从rfc，回应语可以随便定义
smtp client“只”根据这个回应码来判断smtp server的回应情况，而不会理会回应语是什么

看250后面的英文应该还不是多难的
