Dear All,

Can any one tell me how to block bad words in zimbra for every incoming and outgoing mails. I am running zimbra latest open source version on Redhat 5.

Thanks,
Jay Choksi

Well you could either use body_checks in Postfix or create your own SA rule. The downside of the SA rule is that your internal networks will be trusted and will probably not hit the rules anyway.

hi,

acctually my requirement is if any user type banned words in mail like "****" then mail should be blocked and admin should get notification for the same.
if you have any configuration document then please provide me.

Thanks & Regards,
Jay

I do not believe that there is anyway to do this at present. A zimlet would be good for it though if you fancy developing something ?

is it possible to header_check feature of main.cf ?

A couple of reasons why this may be a bad idea :-

1. The bad words may occur legitimately in both regular texts and in attachments.
2. If the message body is encoded with e.g. Base64 the bad words won't get caught.
3. Excessive body checks slow Postfix down.

Therefore I think you would be better creating a SpamAssassin rule and attributing a decent score to it on a hit.

Have a look at the existing rules under /opt/zimbra/conf/spamassassin and see if you could adapt one of them to create your own for your specific requirements.
