你没看错，这一篇的题目就是这一串aaazzz。这几天，公司香港总部的同事反映，收到很多北京分公司同事发来的垃圾邮件，内容没别的，就是标题这一行字母。这下子有我忙的了，成堆的查log，最后结论就是这些az邮件既不是同事电脑中毒后发出的，也不是垃圾邮件冒充同事地址发出的，都是很正经的邮件。那么是谁从中作梗呢？

无奈，求助google了，结果发现，I’m not alone…

对调查很有帮助的是以下几个链接：

起初有人说，国外也有人遇到此问题，怎么能说是咱们GFW的责任呢？我于是特意搜了一下英文的结果：

Yeah, this is strange. Postfix is such a successful package that everthing
is solved within a very short period. But this problem has been floating
arroung for quite some time. Also, I noticed that quite a number of the
problematic hosts are from China. And yes, my problematic server is hosted
in China too.

瞧，中国又多了一种现象，那就是“中国式的SMTP故障”。

最后希望伟大的GFW能够做好事留个名，就说“此邮件被GFW拿下” ，大家一看都清楚了，我这网管的活也好做些，对吧，谢谢先。
