Requirements - SomethingWithHorizons/mailserver GitHub Wiki

The envisioned server requirements are not very demanding as this guide aims to create a personal mail server to host a couple of friends and/or family members (a small company at most):

Knowledge / skill

• Basic understanding of GNU/Linux,
• Basic CLI skills (e.g. Bash),
• Basic Text editor skills (e.g. Vim).

Hardware

• Any modern CPU,
• 1 GB RAM,
• 30 GB storage space (i.e. e-mail/attachment storage),
• 10/100/1000 Mbit/s Ethernet port.

:information_source: E.g. a RaspberryPi 2 system.

Software

• Operating system (e.g. Turris OS),
• Text editor (e.g. Vim).

Network

• Stable broadband internet connection,
• Domain name registration (e.g. example.org), See Network preparation for instructions.
• Static public IP address that is not blacklisted.

:warning: CAUTION Do not use this setup as a enterprise-level mission-critical e-mail server (it my technically work, but it is not tested as such)!
