Chinese emails

[Paul]

Hi

Ive been down this road before and thought I fixed it, however am 
getting some complaints from users again that chinese email is being 
blocked as the filetype rules are saying its a program.

When I run just "file" on the message it returns its an executable, 
however "file -i" returns its text/plain

[root at geneva nAB8qd2B008626]# file msg-23153-1986.txt
msg-23153-1986.txt: COM executable for DOS
[root at geneva nAB8qd2B008626]# file -i msg-23153-1986.txt
msg-23153-1986.txt: text/plain; charset=iso-8859-1

I have added

allow   -   text/plain   -   -

To the top of my filetype.rules.conf - however the message is still 
being blocked with "No Programs Allowed"

Im running version 4.74.16.

Any idea's?

Paul
