I've same experience last month and solved it by improving Zimbra Anti Spam.

Also, take a look on MTR trusted network, you should open only for trusted IP.

Just a clarification on this statement. Zimbra does not generate spam, if you genuinely have spam being sent from your server then either your server has been compromised, a user account has been hacked (do you have good password controls?) or a user machine has been infected.

Have a look in the log files and see what's happening and provide some information on what exactly is happening.
