/etc/exim.conf, /etc/aliases Create the exim configuration files with the following commands: cat >> /etc/aliases << "EOF" postmaster: root MAILER-DAEMON: root EOF exim -v -bi /usr/sbin/exim -bd -q1m To protect an existing /etc/aliases file, we will append these aliases to it if it exists. This file should be checked and duplicate aliases removed, if present. To start and stop exim on system boot/shutdown create the exim boot script with the following commands: cat > /etc/rc.d/init.d/exim << "EOF" #!/bin/sh # Begin $rc_base/init.d/exim # Based on sysklogd script from LFS-3.1 and earlier. # Rewritten by Gerard Beekmans - gerard@linuxfromscratch.org source /etc/sysconfig/rc source $rc_functions case "$1" in start) echo "Starting exim..." loadproc /usr/sbin/exim -bd -q1m ;; stop) echo "Stopping exim..." killproc exim ;; status) statusproc exim ;; restart) $0 stop sleep 1 $0 start ;; *) echo "Usage: $0 {start|stop|status|restart}" exit 1 ;; esac # End $rc_base/init.d/exim EOF chmod 755 /etc/rc.d/init.d/exim Create the run level symlinks with the following commands: cd /etc/rc.d/init.d && ln -sf ../init.d/exim ../rc0.d/K25exim && ln -sf ../init.d/exim ../rc1.d/K25exim && ln -sf ../init.d/exim ../rc2.d/K25exim && ln -sf ../init.d/exim ../rc3.d/S35exim && ln -sf ../init.d/exim ../rc4.d/S35exim && ln -sf ../init.d/exim ../rc5.d/S35exim && ln -sf ../init.d/exim ../rc6.d/K25exim
