International multiple location email server setup

I am a web host admin in Hong Kong. My cPanel / WHM servers are based in Hong Kong. The great firewall of China, long distance and slow local network in China can make receiving emails very slow in China. I was wondering if it would be possible to a set of cPanel / WHM servers such that:

1. Emails can be sent to China server via SSH / secured link
2. Allow people to receive and check emails of the same email account in China server and Hong Kong server

I have seen something like this and wonder if this can be done at cPanel / WHM too:
