I am looking to install and setup Qmail on a Debian machine. I would like to also install some type of webmail interface, virus scanning, admin options, spamassasin, etc. I guess a complete email system. I currently have Debian installed and configured. I had previously looked into using postfix but have read that the qmail is more secure. I would like intuitive and informative way to install these packages. Which ones need to be downloaded with aptituded, or downloaded via wget. Ways to secure my email server (if necessary) and best practices. Links are nice, but often are vague and seldom address all installation needs.
