Foxmail 新版中有一个《邮件特快专递》的功能。起先搞不懂如何用，后来知道要在“工具->系统选项”那边设置“本地 DNS 服务器的IP地址”。 　　觉得这个新功能蛮好用的。不需要通过SMTP代理，可以直接通过本地往邮箱所在的邮件交换器发送邮件。在暑假一开始想在 VC++ 中实现这个功能。用 IRIS 截包后，发现程序中有 mx8.263.net 发送邮箱，不知道这个是什么东西，所以作罢。后来才想到这个就是 263.net 的MX记录主机，原来特快专递的原理就是往这个主机上发送数据就行。-Foxmail is a new version of "Speedpost mail" function. Initially do not understand how to use, we later learned to "tool-gt; System Options "side set up" local DNS server IP addresses. " Think of this new feature very good use. Going through SMTP agents, through direct mail to the local where the mail exchange mail. Beginning in the summer to a VC in achieving this function. With IRIS cut package and found out the mx8.263.net send mail, I do not know what this is, give up. Later 263.net think this is the MX records mainframe, the original Speedpost this principle is to send data on the mainframe on the trip.
