In early 2006, Marshall University laid out a plan to migrate HOBBIT (Figure 1), an HP OpenVMS cluster handling university-wide e-mail services. Plagued with increasing spam attacks, this cluster experienced severe performance degradation. Although our employee e-mail store was moved to Microsoft Exchange in recent years, e-mail routing, mailing list and student e-mail store (including IMAP and POP3 services) were still served by OpenVMS with about 30,000 active users. HOBBIT's e-mail software, PMDF, provided a rather limited feature set while charging a high licensing fee. A major bottleneck was discovered on its external disk storage system: the dated storage technology resulted in a limited disk I/O throughput (40MB/second at maximal) in an e-mail system doing intensive I/O operations.
This is a step by step howto guide to set up a mail server on a GNU / Linux system. It is easy to follow, but you end up with a powerfull secure mail server.
This tutorial will tell you how to setup a basic mail server and attempts to teach you a bit about the Postfix MTA (Mail Transfer Agent) in the process.
