Modoboa is a mail hosting and management platform including a modern and simplified Web User Interface . It provides useful components such as an administration panel or a webmail.
Modoboa is a modular tool. You can use only the features you need and so build a customized environment. Its goal is to become a standalone solution, no need to use heterogeneous software anymore!
Modoboa is for everyone: administrators or end-users, it makes your life easier!
An online demonstration is available. You can test almost everything with it but you won't be able to send messages to external recipients. The content is resetted every two hours.
Modoboa is an open source project. You are free to download the official source tarballs, you can also fetch the latest development version using the repository.
Modoboa is not (yet) a turnkey software. There are some steps to follow before this wonderful tool can be used but don't be afraid, many resources are available to help you.
