They aren't my users though, they are clients of ours using their own SMTP servers that are based in China. (We are in Canada) They are trying to send email to us and its all getting picked off by dspam, I'm assuming because it's all in Chinese. I then have to forward the email to the original recipient (internal user) but the Chinese characters get corrupted in the process and it becomes illegible.
My concern with white listing the IP is the sending server sends mail for a multitude of users from all different companies, and white listing that IP would relay open us up to spam from half of China I can't think of a solution that would accept mail from the specific users but disallow the rest of sending servers users not to spam us. Letting the specific email addresses bypass dspam exposes us to the least amount of risk.

Rather than whitelist by address (which as I said is easily forged), you should be setting up SMTP AUTH, so the users in China still use your server to send mail out. If you find that port 25 is blocked in China, you can use SMTP over SSL (port 465) or SMTP SUBMISSION (port 587).
