比如我收到一封邮件,点击回复,发送到服务器后,服务器怎么知道我回复的是哪一封邮件?
因为要代码实现回复功能
To start with, the reply message should do the following things (which are all convention more than anything else):
To
header should be set to the original message's Reply-To
value, if set, otherwise to the From
value.Subject
header should be set to the value of the original message's Subject
header, but with a "Re: "
prefix (unless it already has one).In-Reply-To
header should be set to the original message's Message-Id
header value.References
header should be set to the original message's References
header value with the original message's Message-Id
value appended to it.网上一搜2分钟答案就出来了。
