The main.sh script goal is to deploy a fully functionnal mail server on a completely clean Debian 9 machine.

The deployed stack is the following :

• nginx as a web server and reverse proxy (for user mail and admin web interfaces)
• postfix as an MTA
• dovecot
• rspamd

Usage instruction

• Clone or download this repository on a clean instance of Debian 9.
• Carefully edit the subscripts/vars.sh file to fit your needs.
• Launch the script with admin priviledges sudo ./main.sh
• Follow the instructions and wait for it to finish
• Carefully read the generated TODO file and follow it's instruction to configure you DNS and securise your server.

Disclaimer

This is a fairly straightforward script made to work on a completely blank Debian 9 machine. Very little safeguards are implemented and once it is started there is no way back ! Use it at your own risks. If your building a new server from scratch then this script may releive you of many tedious tasks. But if you already have a production server on which you want to add an email component then you'd better look toward more complete solutions like iRedMail.
