美国VPS比较自由,上面可以放很多中国不能放的东西,比如色情内容等等,只要符合美国法律,都可放到美国VPS上去。
如果在美国VPS上放了一些违法中国法律的内容,可能这个VPS的IP地址被中国封掉,这样在中国将不能访问这个VPS。
如果是客户故意在VPS上放了一些违法中国法律的内容导致被封,则我们不给更换IP。如果是客户不经意的在VPS上放了某些内容而导致被封,我们可以提供免费更换IP的服务。也就是说我们对专门用来存放违反中国法律内容的VPS不提供更换IP服务。
刚配置的邮件服务器在给hotmail邮箱发邮件的时候,经常会被拒绝,查看邮件日志,显示的错误信息如下:
Oct 22 20:46:20 host1 postfix/smtp[4077]: 29EF597A03: to=, relay=mx1.hotmail.com[65.54.244.8]:25, delay=1.4, delays=0.2/0.01/0.93/0.26, dsn=5.0.0, status=bounced (host mx1.hotmail.com[65.54.244.8] said: 550 DY-001 Mail rejected by Windows Live Hotmail for policy reasons.

给yahoo.com邮箱发信,也发不出去,显示的错误日志如下:
Oct 22 21:06:45 host1 postfix/smtp[4126]: AE67897A03: host b.mx.mail.yahoo.com[66.196.97.250] refused to talk to me: 553 Mail from 58.30.17.82 not allowed – 5.7.1 [BL21] Connections not accepted from IP addresses on Spamhaus PBL; see http://postmaster.yahoo.com/550-bl21.html [550]
按照这两个日志的提示,先去这个网站 http://www.spamhaus.org ,把IP地址从PBL里面移走,怎样从PBL里面移走就不细说了,按照网站的提示操作即可。这个动作大概30分钟之后生效。
30分钟以后效果如何呢?
