[Mimedefang] help with Chinese emails..

[Saisab Pradhan]

I'm using mimedefang 2.52, spamassassin 3.0.4 with the following criteria..

1. if hits >=5, spam report is attached to the email and sent to the 
original recipient.
2. if hits >= 7.5 , the mimedefanged email is redirected to a separate mail 
box.
3. if hits>=10, the email is silently discarded and quarantined.

We have a couple of chinese staffs who work with us. The emails they send 
and receive in chinese (genuine emails) are tagged as spam and is 
redirected to the mail box. I have to forward those emails to them every 
time.  How do I resolve this issue?? I don't want to remove chinese emails 
being scanned for spams. Please help..

Thanks in advance..
