Hi there!

You can block spammers by doing next steps in Kerio

1. Open Kerio Admin Console.

2. Go to Antispam and enable Blacklist servers by putting X on each

3. Update.

4. Enable SPF and Caller ID and at SpamAssasin enable SURBL.

Very important thing now!!!!!!

5. Enable immediately SMTP Greeting delay to 25sec.

6. Enable both POP3 before SMTP and SMTP Authentication.

This is great thing I tell you.

By setting those settings I mentioned you, you'll reduce highly spammers and fake senders.

If you want to add spam score to mail with Chinese characters, you can use this file:

Put it in the same directory as the file and restart the mail server service (not the server itself). SpamAssassin will automatically read the new custom rule file and start scoring mails with the new rules.

Also, you'd be well off following the tips from vitaliok.

(aka non-latin)

Just blocking non-latin letters/words would mean: no mail from almost All the World!

Bad thing.. make sure to enable RBL and other goddies
