Filter Foreign Language Spam

[X-Dimension]

90% of our spam mails are in foreign language, so it would be the best way to block foreign language mails for us, because we don't have contacts in other countries. How can i configure Zimbra to filter foreign language spam?

There is a post in the forum (by me, IIRC) that tells you what you need to do to block foreign spam. Have you also checked this wiki page for some additional tips: Improving Anti-spam system - Zimbra :: Wiki

OK, thank you.

I have found the options "ok_languages" and "ok_locales" and i have set them in /opt/zimbra/conf/spamassassin/local.cf.

Where can i see in Zimbra the mails that was blocked by the spam-filters? Sometimes a mail is blocked that is not spam and i must recover it.

BTW: What are the differents between the config fles "local.cf" and /opt/zimbra/conf/salocal.cf and salocal.cf.in?

If mails are having score above kill percent and are blocked, they cannot be recovered as they must have bounced.

Any changes written to salocal.cf.in are rewritten to salocal.cf. So basically you need to edit salocal.cf.in to changes to take effect in salocal.cf

Any mail that exceeds the Kill percentage is removed from the system (i.e. deleted), it's not a good idea to bounce spam.

These options don't seem to work here. I still get all foreign language spam.

Here is an example of a spam mail header. Spamassassin gives only a score of 1.007.

X-Spam-Flag: NO
X-Spam-Score: 1.007
X-Spam-Level: *
X-Spam-Status: No, score=1.007 tagged_above=-10 required=6.6
tests=[BAYES_50=0.001, HTML_MESSAGE=0.001, RCVD_IN_PBL=0.905,
RDNS_NONE=0.1] autolearn=no

Post some details of what changes you've actually made.

I only add these lines in /opt/zimbra/conf/salocal.cf.in and restarted amavisd
