    Hi,

    I would like to do global filtering of foreign language emails using Spamassasin. I would like to reject emails especially Chinese. I have gone through different docs regarding the same. Below are the ones which I have followed for testing. Meanwhile I could see non are helpful. Still I receive Chinese emails. I have tried to debug the case and found the below error in "/var/log/maillog". Look to have some expert advise on this.

    Hello,

    You'd need to also enable the TextCat plugin referenced at:

    ImproveAccuracy - Spamassassin Wiki

    To do so, add the following line to the /etc/mail/spamassassin/init.pre file:

    Code:
    loadplugin Mail::SpamAssassin::Plugin::TextCat
    Then, restart SpamAssassin via:

    Code:
    /scripts/restartsrv_spamd
    Thank you.

    Hello,

    To update, a symbolic link was created using the below commands to ensure the TextCat SpamAssassin plugin worked as expected:

    Code:
    cd /var/lib/spamassassin/3.004001/
ln -s updates_spamassassin_org/languages languages
    Thank you.

    I once wrote a filter rule to block chinese emails.
    Take a look at all the chinese emails that your recieve and you'll start to spot a few common chinese characters.
    I copied and pasted a few in to a global filter rule, they almost stopped over night.
