Email server on Raspberry PI: a seven steps guide

With this first post I start documenting, step by step, the process of setting up an email server based on a Raspberry Pi card, using open source email programs like Postfix, MailScanner, ClamAV , and SpamAssassin.

n

The aim is to have a low power consumption email server that can run continuosly at home. This task is currently performed by my PC, with a Linux SuSe 12.1 operating system, and with an avarege power consumption of about 70W.

n

Another advantage is to leave the Raspberry Email Server functioning all the time when on holiday for longer periods of time.

This proces starts today with my purchase of the Raspberry PI card.
