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 |
/etc/mail/*
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.

Create the run level symlinks with the following commands:
