[SOLVED] Zimbra Relay Security

[Nox]

In Zimbra 5.0.7, when you install the server fresh, does it need to be secured against people on the internet using it as an SMTP relay?

I don't really know much about that, I just don't want to find out 3-6 months later that someone has been using my server as a spam machine.

Zimbra is not an open relay by default - if you're worried you configured something wrong here's a test you can run: Mail relay testing

I wasn't able to get registered on Abuse.net but I was able to test another way. It is not an open relay. Thanks!
