With the charset being filtered. Could you add *.kr and the ip range to the
config of the mailer or list manager or the firewall that allow you to
RELAY,REJECT etc... aswell ?
Like extra projection ?
Isnt there some law some where about this, I have seen somewhere that state
something like any advertisting/ advertisters will have to play $500 under
rule 2323 section 4328943 line 3 . But if we did find something like that,
how would be able to enforce it and get the money ?

It's not a brilliant idea to filter based on the charset.
(i) The specified charset is correct.
(ii) The specified charset is the lowest upper bound of the
that is actually used.
(i) is OK(ish).
But (ii) is a bit more dodgy.
Since us-ascii is a subset of many other charsets, including
"exotic" ones, it is valid to send an email written
us-ascii characters with the header "charset=foo-bar", if
includes us-ascii as a subset.
Doing this is certainly not good practice, and the actual
lowest-upper-bound charset should be given in the header
But many MUAs generate the Content-type: line according to
setting, not according to the actual content of the message.
it's quite common bad practice.
