11 Install Courier-IMAP, Courier-Authlib, And Maildrop
Unfortunately there are no rpm packages for Courier-IMAP, Courier-Authlib, and Maildrop, therefore we have to build them ourselves.
First remove Dovecot:
yum remove dovecot dovecot-mysql
Then install the prerequisites that we need to build Courier rpm packages:
yum install rpm-build gcc mysql-devel openssl-devel cyrus-sasl-devel pkgconfig zlib-devel pcre-devel openldap-devel postgresql-devel expect libtool-ltdl-devel openldap-servers libtool gdbm-devel pam-devel gamin-devel libidn-devel
RPM packages should not be built as root; courier-imap will even refuse to compile if it detects that the compilation is run as the root user. Therefore we create a normal user account now (falko in this example) and give him a password:
useradd -m -s /bin/bash falko
passwd falko
We will need the sudo command later on so that the user falko can compile and install the rpm packages. But first, we must allow falko to run all commands using sudo:
Run
visudo
In the file that opens there's a line root ALL=(ALL) ALL. Add a similar line for falko just below that line:
[...] ## Allow root to run any commands anywhere root ALL=(ALL) ALL falko ALL=(ALL) ALL [...] |
Now we are ready to build our rpm package. First become the user falko:
su falko
Next we create our build environment:
mkdir $HOME/rpm
mkdir $HOME/rpm/SOURCES
mkdir $HOME/rpm/SPECS
mkdir $HOME/rpm/BUILD
mkdir $HOME/rpm/BUILDROOT
mkdir $HOME/rpm/SRPMS
mkdir $HOME/rpm/RPMS
mkdir $HOME/rpm/RPMS/i386
mkdir $HOME/rpm/RPMS/x86_64
echo "%_topdir $HOME/rpm" >> $HOME/.rpmmacros
Now we create a downloads directory and download the source files from http://www.courier-mta.org/download.php:
mkdir $HOME/downloads
cd $HOME/downloads
wget --no-check-certificate https://sourceforge.net/projects/courier/files/authlib/0.64.0/courier-authlib-0.64.0.tar.bz2/download
wget --no-check-certificate https://sourceforge.net/projects/courier/files/imap/4.9.3/courier-imap-4.9.3.tar.bz2/download
wget --no-check-certificate https://sourceforge.net/projects/courier/files/maildrop/2.5.5/maildrop-2.5.5.tar.bz2/download
(Please note that I use Courier-IMAP 4.9.3 here instead of the newer 4.10.0 because 4.10.0 depends on systemctl which exists for Fedora, but not for CentOS.)
Now (still in $HOME/downloads) we can build courier-authlib:
sudo rpmbuild -ta courier-authlib-0.64.0.tar.bz2
After the build process, the rpm packages can be found in /root/rpmbuild/RPMS/x86_64 (/root/rpmbuild/RPMS/i686 if you are on an i686 system). The command
sudo ls -l /root/rpmbuild/RPMS/x86_64
shows you the available rpm packages:
[falko@server1 downloads]$ sudo ls -l /root/rpmbuild/RPMS/x86_64
total 524
-rw-r--r-- 1 root root 125304 Jul 11 19:09 courier-authlib-0.64.0-1.el6.x86_64.rpm
-rw-r--r-- 1 root root 263700 Jul 11 19:09 courier-authlib-debuginfo-0.64.0-1.el6.x86_64.rpm
-rw-r--r-- 1 root root 37804 Jul 11 19:09 courier-authlib-devel-0.64.0-1.el6.x86_64.rpm

[falko@server1 downloads]$
Select the ones you want to install, and install them like this:
sudo rpm -ivh /root/rpmbuild/RPMS/x86_64/courier-authlib-0.64.0-1.el6.x86_64.rpm /root/rpmbuild/RPMS/x86_64/courier-authlib-mysql-0.64.0-1.el6.x86_64.rpm /root/rpmbuild/RPMS/x86_64/courier-authlib-devel-0.64.0-1.el6.x86_64.rpm
Now we go back to our downloads directory:
cd $HOME/downloads
Run the following commands to create required directories/change directory permissions (because otherwise the build process for Courier-Imap will fail):
sudo mkdir -p /var/cache/ccache/tmp
sudo chmod o+rwx /var/cache/ccache/
sudo chmod 777 /var/cache/ccache/tmp
Now run rpmbuild again, this time without sudo, otherwise the compilation will fail because it was run as root:
rpmbuild -ta courier-imap-4.9.3.tar.bz2
After the build process, the rpm packages can be found in $HOME/rpm/RPMS/x86_64 ($HOME/rpm/RPMS/i686 if you are on an i686 system):
cd $HOME/rpm/RPMS/x86_64
The command
ls -l
shows you the available rpm packages:
[falko@server1 x86_64]$ ls -l
total 1108
-rw-rw-r-- 1 falko falko 331736 Jul 12 15:17 courier-imap-4.9.3-1.x86_64.rpm
-rw-rw-r-- 1 falko falko 800664 Jul 12 15:17 courier-imap-debuginfo-4.9.3-1.x86_64.rpm
[falko@server1 x86_64]$
You can install courier-imap like this:
sudo rpm -ivh courier-imap-4.9.3-1.x86_64.rpm
Now we go back to our downloads directory:
cd $HOME/downloads
and run rpmbuild again, this time to build a maildrop package:
sudo rpmbuild -ta maildrop-2.5.5.tar.bz2
After the build process, the rpm packages can be found in /root/rpmbuild/RPMS/x86_64 (/root/rpmbuild/RPMS/i686 if you are on an i686 system). The command
sudo ls -l /root/rpmbuild/RPMS/x86_64
shows you the available rpm packages:
[falko@server1 downloads]$ sudo ls -l /root/rpmbuild/RPMS/x86_64
total 1708

[falko@server1 downloads]$
You can now install maildrop like this:
sudo rpm -ivh /root/rpmbuild/RPMS/x86_64/maildrop-2.5.5-1.x86_64.rpm
After you have compiled and installed all needed packages, you can become root again by typing
exit
Now start Courier-IMAP/-POP3 as follows:
/etc/init.d/courier-imap start
12 Install Postfix
Postfix can be installed as follows:
yum install postfix
Then turn off Sendmail and start Postfix:
chkconfig --levels 235 sendmail off
chkconfig --levels 235 postfix on
/etc/init.d/sendmail stop
/etc/init.d/postfix restart
13 Install Getmail
Getmail can be installed as follows:
yum install getmail
14 Install Amavisd-new, SpamAssassin And ClamAV
To install amavisd-new, spamassassin and clamav, run the following command:
yum install amavisd-new spamassassin clamav clamd unzip bzip2 unrar perl-DBD-mysql
Then we start freshclam, amavisd, and clamd.amavisd:
sa-update
chkconfig --levels 235 amavisd on
chkconfig --del clamd
chkconfig --levels 235 clamd.amavisd on
/usr/bin/freshclam
/etc/init.d/amavisd start
/etc/init.d/clamd.amavisd start
