今天无意中从日志里发现的, 真是服了它, 有人也是这样做的吗?

似乎有点像CanIt-PRO呢

钉子

网上找到一个类似信息难不成他们用了Canit-PRO反垃圾?


Reject spam with CanIt-PRO

Canit-PRO has a sendmail dependency. If you already run sendmail, however, that shouldn't be a problem. Otherwise, you might want to run it on its own server with sendmail.

When CanIt-PRO is told to reject mail, and it recognizes an incoming message as spam, it issues the following error to the sending server: "451 4.3.0 Message held for human verification before permitting delivery. For help, please quote incident ID 2." The ID number will change, of course.

This is particularly useful, and polite, for administrators of other mail servers. If CanIt-PRO does identify legitimate email as spam, it means that the user on the other end is going to be wondering why his mail is being returned.

不太理解啊

钉子, 这家公司的做法和你不太同,
451 4.3.0 Message held for human verification before permitting delivery.  For help, please quote incident ID 677756.,
由于返回码是451, 发送方服务器收到这个信息并不会把它发给发件人, 而是继续重试, 直到对方允许发出去, 或超过规定的发送时间退信给发件人.

没错.我经常发一些邮件给国外的厂商,他们回复时就会在邮件的主题中加上编号.应该是先放到服务人员工作队列中排程处理.

正常，老外有的系统很厉害，需要人工审核-未必是针对垃圾，可能是订单，咨询，support，有的系统和内部CRM连起来的，不审核以下内部系统爆了。
其实是工作流的一部分。

太牛了～～

砸锅卖铁

应该也是针对敏感内容吧
