While installing my G4 mini with the new mailserver setup I found some minor mistakes in the documentation. Some of the settings where changed on the test server to get it working and they didn’t make it into my notes. That is corrected now.
Also I’ve incorporated the SSL and TLS settings into the default setup instead of making them a separate set of instructions. I think you should not have a mailserver without it.
As a last addition before I start documenting the setup on Tiger I’ve included a page with instructions on how to be able to test your setup. I hope you find them usefull.
