The exim package contains a Mail Transport Agent written by the University of Cambridge, released under the GNU Public License.
exim depends on: db-4.1.25 |
Before building exim, we need to create a user and group for exim with the following commands:
groupadd exim useradd -d /dev/null -g exim -s /bin/false exim |
Install exim with the following commands:
sed -e 's/^BIN_DIR.*$/BIN_DIRECTORY=\/usr\/sbin/' src/EDITME | \ sed -e 's/^CONF.*$/CONFIGURE_FILE=\/etc\/exim.conf/' | \ sed -e 's/^EXIM_USER.*$/EXIM_USER=exim/' | \ sed -e 's/^EXIM_MONITOR/#EXIM_MONITOR/' > Local/Makefile && make && make install && ln -s /usr/sbin/exim /usr/sbin/sendmail |
/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 |
Note: 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

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 |

ln -s /usr/sbin/exim /usr/sbin/sendmail : Create a link to sendmail for applications which need it. exim will accept most Sendmail command line options.
