In this work, we propose the implementation of a Distributed Platform for Massively Emails distribution, called OPTIMUS (OPTImized Mail distribUtion System). It allows efficient workload distribution among multiples email servers, optimizes the use of available resources, and provides fault tolerance in a robust distribution platform. OPTIMUS architecture extends the Postfix server implementation to incorporate data base management, workload balance, and fault tolerance. It is composed by several extended Postfix servers, connected in a Peer-to-Peer platform. Experimental results show that with a few amount of emails, Postfix (with its original centralized implementation) and OPTIMUS have similar performance. However, with huge amount of emails, OPTIMUS highly overcomes the performance of the original centralized Postfix version.
