Before building Sendmail, we need to create users, groups and directories that sendmail uses with the following commands:
groupadd smmsp && groupadd mail && useradd -g smmsp -G mail smmsp && chmod 1777 /tmp && chmod 1777 /var/mail && mkdir /var/spool/mqueue |
Install Sendmail with the following commands:
cat > devtools/Site/site.config.m4 << "EOF" define(`confMANGRP',`root') define(`confMANOWN',`root') define(`confSBINGRP',`root') define(`confUBINGRP',`root') define(`confUBINOWN',`root') EOF cd sendmail && sh Build && cd ../cf/cf && cp generic-linux.mc sendmail.mc && mkdir /etc/mail && sh Build sendmail.mc && sh Build install-cf && cd ../../ && sh Build install |
echo `hostname` > /etc/mail/local-host-names cat > /etc/mail/aliases << "EOF" postmaster: root MAILER-DAEMON: root EOF cd /etc/mail && cp -R /usr/src/sendmail-8.12.10/cf/* . && cp -R /usr/src/sendmail-8.12.10/cf/cf/submit.mc . && cp -R /usr/src/sendmail-8.12.10/cf/cf/sendmail.mc . && newaliases -v |
To start and stop Sendmail on system boot/shutdown create the sendmail boot script with the following commands:
Note: The -qNm option, where N is number of minutes, controls how often Sendmail will process the mail queue. A default of 5 minutes is used here. Individual workstation users may want to set this as low as 1 minute, large installations handling more mail will want to set it higher.
cat > /etc/rc.d/init.d/sendmail << "EOF" #!/bin/sh # Begin $rc_base/init.d/sendmail # Based on sysklogd script from LFS-3.1 and earlier. # Rewritten by Gerard Beekmans - [email protected] source /etc/sysconfig/rc source $rc_functions case "$1" in start) echo "Starting sendmail..." loadproc /usr/sbin/sendmail -bs -bd -q5m start ;; stop) echo "Stopping Sendmail..." killproc sendmail ;; status) statusproc sendmail ;; restart) $0 stop sleep 1 $0 start ;; *) echo "Usage: $0 {start|stop|status|restart}" exit 1 ;; esac # End $rc_base/init.d/sendmail EOF chmod 755 /etc/rc.d/init.d/sendmail |
Create the run level symlinks with the following commands:
cd /etc/rc.d/init.d && ln -sf ../init.d/sendmail ../rc0.d/K25sendmail && ln -sf ../init.d/sendmail ../rc1.d/K25sendmail && ln -sf ../init.d/sendmail ../rc2.d/K25sendmail && ln -sf ../init.d/sendmail ../rc3.d/S35sendmail && ln -sf ../init.d/sendmail ../rc4.d/S35sendmail && ln -sf ../init.d/sendmail ../rc5.d/S35sendmail && ln -sf ../init.d/sendmail ../rc6.d/K25sendmail |
