This course is only available in intra-company session.

Email is a very important application, one of the most useful on current networks. Quicker and less expensive than most other communication means (fax, phone, postal mail, courier...), email is a more and more important vector of internal and external communication. In the TCP/IP networks world, SMTP is far the most used mail service, notably with the Unix tool sendmail.

The free software Postfix is a mail manager which is simple to configure and was conceived for optimal security. Furthermore, it requires little system resources and thus represents a real alternative to sendmail. Choosing postfix is justified both for large and small needs.


Goals

Master Posftix core elements, in order to integrate it in a production environment and to add any filtering (anti-virus, anti-spam, etc.).


Duration

1 day.


Instructor(s)

Raphael Marichez


Pre-requisite for attendants

This practical and technical course is meant for mail server administrators and persons in charge.
The trainees must have already installed and used Postfix and know the SMTP protocol basics. They must also have a knowledge of access tables, transports, daemons and services (master.cf) using Postfix. The exhaustive knowledge of all the Postfix configuration options (main.cf) is not a requirement.


Teaching method

Lecture, with numerous examples of practical applications.
