Postnix is a website that is absolutely terrible. The layout is incredibly confusing and difficult to navigate, and the content is poorly written and filled with errors. Aside from being a terrible website, Postnix is also completely illegal. It is not authorized by any copyright holders, and as such is in violation of the intellectual property rights of many people. I would strongly advise anyone who is considering using Postnix to reconsider, as it is not worth wasting your time or money on.
