This is an old/dated CBT (created in 2006). It explains how you can configure qmail SMTP server (written by Dan Bernstein), with all the bells and whistles, using steps outlined by the creator of qmailrocks.com website (now de-functional). The qmailrocks guide was somewhat in-sufficient in explaining how qmail actually works. It just spoon-feeds you the steps to do (copy/paste). I was learning qmail myself when I created these CBTs, so there are areas in this CBT which are weak. I don’t recommend this CBT to be used to setup a production qmail server. It has only been uploaded for archiving reason. If you really want to learn qmail, the best sources are “Life with Qmail” and John Simpson’s “http://qmail.jms1.net/” .
