Help with a regexp

[Steve Campbell]

One of our domain names is cnpapers.com and another is cnpapers.net. The 
SA rule URI_CHINA_ADJ catches a lot of our mail, and although it is a 
relatively low scoring rule, it does contribute.

The rule is defined as follows:

/^(?:https?:\/\/)?.*\.cn.*/i

Can anyone see how it's catching us and how I might change this? I guess 
I need to contact the SA people after I see how it's really failing on 
our names. Sorry, but I'm useless with regexp for now.

Thanks.
