Spamassasin filter foreign language emails

[nisamudeen97]

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,

Could you let us know the specific changes you made to the /etc/mail/spamassassin/local.cf file?

Thank you.

Hi,

I just added the below line as extra in /etc/mail/spamassassin/local.cf, rest of the things are default.

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:

loadplugin Mail::SpamAssassin::Plugin::TextCat

Then, restart SpamAssassin via:

/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:

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.
