TX不用卖邮件地址，专门有工具采集邮件地址。看起来主要还是qqmail对垃圾邮件过滤还是偏弱
没有反向解析，没有spf，这样的域名和ip应该是被扔到垃圾邮箱的。
先查域名情况
nslookup
youxi.baidu.com 8.8.8.8
Server: 8.8.8.8
Address: 8.8.8.8#53
Non-authoritative answer:
youxi.baidu.com canonical name =
game.n.shifen.com.
Name:
game.n.shifen.comAddress: 123.125.115.241
然后发现这个域名没有SPF。。TXT是空的
dig txt
game.n.shifen.com; <<>> DiG 9.8.1-P1 <<>> txt
game.n.shifen.com;; global options: +cmd
;; Got answer:

game.n.shifen.com. IN TXT

ns1.n.shifen.com.
baidu_dns_master.baidu.com. 1306060012 60 30 86400 3600
然后看这个IP是哪里的
whois 123.125.115.241

最终发现没有没有反向解析。。
nslookup 123.125.115.241 8.8.8.8
