Getting, building, and installing qmail

1. Get qmail (http://koobera.math.uic.edu/qmail.html)
2. Set up qmail users
3. Build and install qmail
4. A special consideration for RedHat is that qmail for security reasons does not deliver to home directories that are group writable. RedHat systems use user-groups extensively, i.e. each user is the sole member of a group with the user's name. You can change this, or change conf-patrn to "002" before building qmail.
5. Init file for qmail/linux
6. My init file for qmail on RedHat Linux
7. Startup links for qmail on RedHat
8. Protential problems
   • Qmail paternalism (see above)
   • Bare line feed rejecction (see www.qmail.org).
9. Qmail Additions
   • tcpserver (ucspi-tcp) to reliably start daemons and modify their behavior depending on the connecting client (by DJB, see Dan's WWW site).
   • daemontools to reliably keep daemons running, rotate logs, etc (by DJB, see Dan's WWW site).
   • analog to analyze and summarize qmail logs (by DJB, see Dan's WWW site).
   • Various qmail patches, including powerful anti-spam features (by several authors, see www.qmail.org).
