不使用smtp直接发送邮件
用smtp发邮件挺蛋疼的,不是有配额限制就是有配额限制.所以我觉得应该有直接发送邮件的办法.回归到用命令行装逼的年代,我们是这样发信的:
C:\>nslookup
默认服务器: google-public-dns-a.google.com
Address: 8.8.8.8
> set type=mx
> qq.com
服务器: google-public-dns-a.google.com
Address: 8.8.8.8
非权威应答:
qq.com MX preference = 10, mail exchanger = mx3.qq.com
qq.com MX preference = 20, mail exchanger = mx2.qq.com
qq.com MX preference = 30, mail exchanger = mx1.qq.com
C:\>telnet mx3.qq.com 25
220 newmx13.qq.com MX QQ Mail Server
