roddy Posted April 12, 2006 at 05:54 AM Report Share Posted April 12, 2006 at 05:54 AM Just a quick heads up for people here. Most of us located in China know that internet traffic is filtered and that if you try and load up pages containing certain keywords, your access to that site will be blocked for several minutes. Since somehow ending up on mailing lists for a few non-China friendly groups based abroad, I've found this also applies to POP3 mail access. Everytime I get an email containing aforementioned keywords, Thunderbird loses the connection to the server shortly after logging in, and can't regain it for a few minutes. This also knocks out my http access to sites on the same server. Not sure if it affects ftp. The only solution I've found to this is to log onto webmail (via a proxy, or your connection will cut out, remember . . .) and delete the offending messages. Probably not a major issue for most people, but may save someone a bit of troubleshooting if they know what's happening in advance.

stephanhodges Posted April 12, 2006 at 12:20 PM Report Share Posted April 12, 2006 at 12:20 PM Does that happen with sending email, or just recieving? Could be used as an email equivalent to a DOS attack, hmm? Quote Link to comment Share on other sites More sharing options...
roddy Posted April 12, 2006 at 03:02 PM Author Report Share Posted April 12, 2006 at 03:02 PM Not exactly a DOS attack, but you could certainly annoy someone. Annoys me, anyway. I don't know what happens with sending. Is SMTP encoded at all? I have never noticed any problems, but I wouldn't because I'm a good little boy.

Long Zhiren Posted April 13, 2006 at 06:52 PM Report Share Posted April 13, 2006 at 06:52 PM Does this filtering happen for correspondance to Hong Kong too? It's hard to know either if someone's even getting my messages or simply ignoring them... Quote Link to comment Share on other sites More sharing options...
roddy Posted April 14, 2006 at 12:36 AM Author Report Share Posted April 14, 2006 at 12:36 AM To Hong Kong from the US? No, I don't think so. To Hong Kong from China, yes on China side. Quote Link to comment Share on other sites More sharing options...
stoney Posted April 14, 2006 at 01:56 AM Report Share Posted April 14, 2006 at 01:56 AM I'll be in China next year. I wonder if my outgoing emails will be filtered? what sort of language/words are triggers. Would information in attachments also be filtered?

roddy Posted April 14, 2006 at 02:46 AM Author Report Share Posted April 14, 2006 at 02:46 AM I've never had any trouble with out going mail, the only 'issue' is with incoming Chinese-language spam from anti-China groups abroad. If that was just blocked by the filters I would be quite happy (can they get rid of all the other spam too?) but the problem is it cuts off your access to your mail server for a few minutes. Basically unless you are sending Chinese language anti-China (and particularly anti-Party) material, then you will have no problems at all. Don't worry about it.
