Building Postfix

The Postfix .rpm binaries do not come with mysql support enabled- therefore you must compile your own. Download the Postfix SRPM and build the packages this way:

rpm -ivh postfix.src.rpm
cd /usr/src/redhat/SPECS

Fire up your favorite text editor and edit postfix.spec
Change the line from:

%define MYSQL 0

to:

%define MYSQL 1

Exit editor, then:

cd ../
rpmbuild -ba SPEC/postfix.spec

(It will take a while to finish compiling)

cd RPMS/i386

Then, install the RPMs:

rpm -Uvh *.rpm --replacefiles
