Install Postfix + courier + MySQL in RedHat

Prepare the compilation environment: # yumgroupinstall 'developmenttool' # yumgroupinstall 'developmentlibraries' # yuminstallmysql-develpostgresql-develexpectlibtool-ltdl-develgamin-develpcre-devel must be compiled under normal users.

Preparations
Install the compiling environment:

# Yum groupinstall 'development tool'
# Yum groupinstall 'development libraries'
# Yum install mysql-devel postgresql-devel submit CT libtool-ltdl-devel gamin-devel pcre-devel
During compilation, you need to add a user under a common user:

# Useradd username
# Passwd username
Use the "cmddo" command to configure sudo and add users:

Root ALL = (ALL) ALL
Username ALL = (ALL) ALL
Switch to this user:

# Su username
Create a working directory:

$ Mkdir $ HOME/rpm
$ Mkdir $ HOME/rpm/SOURCES
$ Mkdir $ HOME/rpm/SPECS
$ Mkdir $ HOME/rpm/BUILD
$ Mkdir $ HOME/rpm/SRPMS
$ Mkdir $ HOME/rpm/RPMS
$ Mkdir $ HOME/rpm/RPMS/i386

$ Echo "% _ topdir $ HOME/rpm"> $ HOME/. rpmmacros

Mkdir $ HOME/downloads
Install Postfix
Because the Postfix package of RedHat does not support MySQL, We Need To package a new version.

Download and install the source code package:

# Wget http://ftp.wl0.org/official/2.5/SRPMS/postfix-2.5.9-1.src.rpm
# Rpm-ivh postfix-2.5.9-1.src.rpm
Modify compilation parameters:

# Cd/usr/src/redhat/SPECS
# Vi postfix. spec
Set the following content in "postfix. spec:

% Define with_cdb 0
% Define with_ldap 1
% Define with_mysql 0
% Define with_mysql_redhat 0
% Define with_pcre 0
% Define with_pgsql 0
% Define with_sasl 0
% Define with_spf 0
% Define with_dovecot 0
% Define with_tls 1
% Define with_tlsfix 2
% Define with_vda 0
To:

% Define with_cdb 0
% Define with_ldap 0
% Define with_mysql 0
% Define with_mysql_redhat 1
% Define with_pcre 0
% Define with_pgsql 0
% Define with_sasl 2
% Define with_spf 0
% Define with_dovecot 1
% Define with_tls 1
% Define with_tlsfix 2
% Define with_vda 0
Re-create rpm package:

# Rpmbuild-ba postfix. spec
Install the new package Postfix:

# Cd/usr/src/redhat/RPMS/i386
# Rpm-ivh postfix-2.5.9-1.rhel5.i386.rpm

To implement SMTP mail authentication, you must install the "cyrus-sasl" program and directly use YUM to install it:

# Yum install cyrus-sasl-SQL
Install other common software:

# Yum install fetchmail mutt
