INSTALL INSTRUCTIONS

This is basically my HOW-TO install sendmail on a Redhat system with POP before SMTP authorization.  
These instructions were tested and written using various Redhat 5.X to 7.X servers and these exact 
instructions are for RedHat 7.1.

Uninstall the default sendmail that comes with the OS, but save some of the important files:
	mkdir /tmp/sendmail-save
	cd /tmp/sendmail-save
	tar cvfz sendmail-save.tar.gz /etc/rc.d/init.d/sendmail /etc/sendmail.cf /etc/aliases /etc/mail/ /etc/pam.d/smtp /etc/sysconfig/sendmail /usr/lib/sasl/Sendmail.conf


Build the Source:
	cd /usr/src/
	tar zxvf /<wherever>/sendmail.8.11.3.tar.gz
	cd sendmail-8.11.3

	cp sendmail.mc to /usr/src/sendmail-8.11.3/cf/cf
	cp popauth.m4 to /usr/src/sendmail-8.11.3/cf/hack

	#RH 7.X Change -- This fixes some non standard paths that Redhat uses
	cp Linux-OS /usr/src/sendmail-8.11.3/devtools/OS/Linux


	sh Build
	sh Build install

	cd cf/cf
	sh Build sendmail.cf

Install the Configuration files / Make dirs / etc.
	mkdir /etc/mail
	mkdir /var/spool/mqueue
	chmod 755 /etc/mail /var/spool/mqueue
        chown root.mail /var/spool/mqueue

	cp sendmail.* /etc/mail/

	#NOTE: Poprelayd-KAM requires DB_File which is an ext module of perl and may need to be manually installed.  
	#    i.e. 'cd /usr/src/perl-5.6.1/ext/DB_Files/; perl Makefile.PL; make; make install'
	makemap hash /etc/mail/popauth.db < /dev/null

	cp poprelayd-KAM.pl /usr/local/sbin/
	chmod +x /usr/local/sbin/poprelayd-KAM.pl
	###Add Poprelay Daemon to /etc/rc.d/rc.local (i.e. add a line that says this /usr/local/sbin/poprelayd-KAM.pl -d)
        
	###run Poprelay delay
        /usr/local/sbin/poprelayd-KAM.pl -d

#Restore Saved files and Move files to proper locations
	cd /tmp/sendmail-save
        tar zxvf sendmail-save.tar.gz
        mv /tmp/sendmail-save/etc/rc.d/init.d/sendmail /etc/rc.d/init.d
