E-mail server - Exim, anti-spam solutions

Category: Linux administration

Designing and deploying an efficient e-mail delivery system based on the Exim MTA. Course participants learn about configuring and managing Exim both as a standalone server (authorization using system accounts and external databases, various virtual domain setups) and as a gateway for a Microsoft Exchange server. Advanced state-of-the-art spam- and virus-fighting techniques are discussed (bayesian filters, DKIM, OpenSPF, selective greylisting, verification at early stages of SMTP conversation).

During the course participants get hands-on experience as they configure a working mail server that mimics real-world SMTP operation.
