Hello,

We are trying out Zimbra and so far it has been working out great! There is 1 problem though, we have written a script which connects to zimbra with pre-defined credentials and shoots out tons of emails to 1 email id. This is just a testing phase to see how Zimbra performs under stress.

Here is the problem though, after some time it is kicking out the remote IP address.

Below is the error from logs.
