Re: english text only?

Previous posts indicate that the list owner, gnu.org. does not believe
in filtering.  Not sure what their stand on open relays is, but they
will not filter or block email.

I don't like blocking entire domains either, so I came up with a
solution that only blocks Asian language email.  It uses the Subject:
and Content-Type: headers to isolate the character set and blocks the
most common Asian types.  This is a postfix header_check file.  You'll
need to adapt it to your client or mailer as needed.

# header checks to kill Asian language spam

/^Subject:.*=\?big5\?/                          REJECT
/^Content-Type:.*charset=.*big5/                REJECT

/^Subject:.*=\?euc-kr\?/                        REJECT
/^Content-Type:.*charset=.*euc-kr/              REJECT

/^Subject:.*=\?gb2312\?/                        REJECT
/^Content-Type:.*charset=.*gb2312/              REJECT

/^Subject:.*=\?iso-.*-jp\?/                     REJECT
/^Content-Type:.*charset=.*iso-.*-jp/           REJECT

/^Subject:.*=\?koi8\?/                          REJECT
/^Content-Type:.*charset=.*koi8-r/              REJECT

/^Subject:.*=\?ks_c_5601-1987\?/                REJECT
/^Content-Type:.*charset=.*ks_c_5601-1987/      REJECT

This is only a start, but its shown good sucess for getting rid of the
gibberish without nuking anything you might want.

...Thanks,
...Kenneth
