更改qmail的失败通知消息

我想编辑每次邮件无法发送时由qmail通过邮局主pipe帐户发送的邮件。

原始信息如下:

Hi. This is the qmail-send program at xxxx.com. I'm afraid I wasn't able to deliver your message to the following addresses. This is a permanent error; I've given up. Sorry it didn't work out. <[email protected]>: Sorry, I couldn't find any host named xxxx.com. (#5.1.2) --- Below this line is a copy of the message. 

这样做的原因是因为我的客户是葡萄牙人,所以没有必要用英语发送这个消息。 我也想重新说一下。

我似乎无法findconfiguration上的任何事情。

有了股票qmail,只能在源代码中更改该消息。
