As you may know it, an installer is available to deploy a complete mail server based on Modoboa:
> git clone https://github.com/modoboa/modoboa-installer > cd modoboa-installer > sudo ./run.py mail.example.tld
Until now, only debian based distributions were supported but we're happy to announce CentOS has been added to the list ! Tests have been made on version 7 only but any feedback about other versions are welcome.
Another interesting update concerns security. The installer now generates a self-signed certificate using the hostname provided on the command line as Common Name. It is just a beginning as we know the certifcate will still be considered as invalid. The next step, which should come soon, is to add support for Let's Encrypt.
We hope those features will be useful and as always, we wait for your feedback :-)
