Is your mail server an open relay?

Some of you may already know about this but for those who don’t or forgot. After setting up your mail server you should run a mail relay test. This will run several tests against your MTA and verify it’s properly configured. By default Zimbra ships postfix such that it’s not a relay. However any custom config may open your server up for abuse. Always better to check before a spammer finds you!
