Email downloading and Internet controls

Mr Liu Zhengrong, the man at the State Council responsible for the Great Firewall of China, filtering the Internet for the masses, says that the controls on content are fundamentally the same as those implemented by other countries. I don’t know, but when I am in China, my downloading of emails is regularly impeded by individual emails that are blocked for whatever reason by the local ISP. If I then travel to somewhere outside of the mainland such as Hong Kong or Tokyo, the problem immediately clears, and the emails fall off the server and into my Outlook inbox smoothly. Why? I presume it is filtering of email content on a keyword basis. There is a way round it – use webmail interfaces and read and delete the offending emails. That unblocks the queue and the emails then come in. For me, a wasted 20 minutes. For China, an impediment to the growth of business.
