Check /var/log/zimbra.log for any erroneous activity.

su - zimbra
zmprov gacf | grep -i mtarestriction

well thanks for the reply ..while executing the command you've provided I'm getting the following reply:

zimbra@mail:/$ zmprov gacf | grep -i mtarestriction
zimbraMtaRestriction: reject_invalid_hostname
zimbraMtaRestriction: reject_non_fqdn_sender

can you please comment on that.

I would recommend that you have a read through Wiki :: Improving Anti-Spam System and implement some of the methods as this will help to improve your system. Especially using some of the RBLs as this will reject SPAM at the Postfix level and hence reduce the load on your system.

thanks uxbod for the links you've provided..

I would highly recommend implementing the RBL from Barracude Central as I have seen a large reduction in the amount of SPAM that makes it through the perimeter services.
