Configuring a mail server is not actually difficult, but it takes a little bit more than inserting an installation CD anyway. Luckily, there is Postfix, because since this SMTP server - created by award-winning programmer Wietse Venema - entered the market, you may ask yourself why others do make email so difficult.
At the end of an engaging and diversified week, you understand how email works, master the different varieties of mail transport, control email at your will with Postfix and expertly defeat spam and co.
Your trainer will be Patrick Ben Koetter, who will not only teach you the tricks of the trade, but also is going to show to you how to break your dependence on Closed Source and expensive support by ways of Postfix and the right know-how.
