-Things you have to decide before starting:
-
-* The qmail home directory, normally /var/qmail. To change this
-directory, edit conf-qmail now.
-
-* The names of the qmail users and the qmail groups. To change these
-names, edit conf-users and conf-groups now.
-
-
-To create /var/qmail and configure qmail (won't interfere with sendmail):
-
- 1. Create the qmail home directory:
-       # mkdir /var/qmail
-
- 2. Read INSTALL.ids. You must set up the qmail group and the qmail
-    users before compiling the programs.
-
- 3. Compile the programs and create the qmail directory tree:
-       # make setup check
-
- 4. Read INSTALL.ctl and FAQ. Minimal survival command:
-       # ./config
-
- 5. Read INSTALL.alias. Minimal survival command:
-       # (cd ~alias; touch .qmail-postmaster .qmail-mailer-daemon .qmail-root)
-       # chmod 644 ~alias/.qmail*
-
- 6. Read INSTALL.mbox and INSTALL.vsm.
-
- 7. Read INSTALL.maildir.
-
- 8. Copy /var/qmail/boot/home (or proc) to /var/qmail/rc.
-
-
-To test qmail deliveries (won't interfere with sendmail):
-
- 9. Enable deliveries of messages injected into qmail:
-       # csh -cf '/var/qmail/rc &'
-
-10. Read TEST.deliver.
-
-
-To upgrade from sendmail to qmail:
-
-11. Read SENDMAIL. This is what your users will want to know about the
-    switch from sendmail to qmail.
-
-12. Read REMOVE.sendmail. You must remove sendmail before installing
-    qmail.
-
-13. Read REMOVE.binmail.
-
-14. Add
-            csh -cf '/var/qmail/rc &'
-    to your boot scripts, so that the qmail daemons are restarted
-    whenever your system reboots. Make sure you include the &.
-
-15. Make qmail's ``sendmail'' wrapper available to MUAs:
-       # ln -s /var/qmail/bin/sendmail /usr/lib/sendmail
-       # ln -s /var/qmail/bin/sendmail /usr/sbin/sendmail
-    /usr/sbin might not exist on your system.
-
-16. Set up qmail-smtpd in /etc/inetd.conf (all on one line):
-            smtp stream tcp nowait qmaild /var/qmail/bin/tcp-env
-            tcp-env /var/qmail/bin/qmail-smtpd
-
-17. Reboot. (Or kill -HUP your inetd and make sure the qmail daemons
-    are running.)
-
-18. Read TEST.receive.
-
-
-
-That's it! To report success:
-       % ( echo 'First M. Last'; cat `cat SYSDEPS` ) | mail djb-qst@cr.yp.to
-Replace First M. Last with your name.
