Sendmail-8.13.3

The Sendmail package contains a Mail Transport Agent (MTA).

Before building Sendmail, create the users, groups and directories that Sendmail requires with the following commands issued as the root user:

groupadd smmsp &&
groupadd mail &&
useradd -c "Sendmail Daemon" -g smmsp -G mail smmsp &&
chmod 1777 /var/mail &&
mkdir /var/spool/mqueue

Note: See the source tree sendmail/README file for information on linking optional packages into the build. Use the example below, which adds support for tcpwrappers, SASL, StartTLS (OpenSSL) and OpenLDAP, as a starting point. Of course, modify it to suit your particular needs.

cat >> devtools/Site/site.config.m4 << "EOF"
APPENDDEF(`confENVDEF',`-DSTARTTLS -DTCPWRAPPERS -DSASL -DLDAPMAP')
APPENDDEF(`confLIBS', `-lssl -lcrypto -lwrap -lsasl2 -lldap -llber')
APPENDDEF(`confINCDIRS', `-I/usr/include/sasl')
EOF

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 &&
sh Build sendmail.cf

Now, as the root user:

install -v -d -m755 /etc/mail &&
sh Build install-cf &&
cd ../../ &&
sh Build install &&
cp -v -R cf/* /etc/mail &&
cp -v cf/cf/{submit,sendmail}.mc /etc/mail &&
for manpage in sendmail editmap mailstats makemap praliases smrsh 
do
    install -v -m444 $manpage/$manpage.8 /usr/share/man/man8
done &&
install -v -m444 sendmail/aliases.5    /usr/share/man/man5 &&
install -v -m444 sendmail/mailq.1      /usr/share/man/man1 &&
install -v -m444 sendmail/newaliases.1 /usr/share/man/man1 &&
install -v -m444 vacation/vacation.1   /usr/share/man/man1

Install the Sendmail Installation and Operations Guide with the following commands:

cd doc/op &&
sed -i -e 's/groff/GROFF_NO_SGR=1 groff/' Makefile &&
make op.txt op.pdf

Now, as the root user:

install -v -d -m755 /usr/share/doc/sendmail-8.13.3 &&
install -v -m644 op.ps op.txt op.pdf \
    /usr/share/doc/sendmail-8.13.3 &&
cd ../../

Note: remove op.pdf from the make and install commands if you don't have Ghostscript installed.

cat > devtools/Site/site.config.m4 << "EOF": This creates a configuration file changing some of the default settings.

sh Build; sh Build sendmail.cf; sh Build install-cf; sh Build install: Sendmail uses an m4 based build script to create the various Makefile's. These commands build and install the package.

for manpage in...;do...;done; install ...: The man pages are installed already formatted and man displays them somewhat garbled. These commands replace the formatted pages with pages man can display properly.
