10 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.
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 (compileuser in this example) and give him a password:
useradd -m -s /bin/bash compileuser
passwd compileuser
We will need the sudo command later on so that the user compileuser can compile and install the rpm packages. But first, we must allow compileuser 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 compileuser just below that line:
[...] root ALL=(ALL) ALL compileuser ALL=(ALL) ALL [...] |
Now we are ready to build our rpm package. First become the user compileuser:
su compileuser
Next we create our build environment:
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
mkdir $HOME/rpm/RPMS/x86_64
echo "%_topdir $HOME/rpm" >> $HOME/.rpmmacros
Now we download the source files from http://www.courier-mta.org/download.php:
cd /tmp
wget http://prdownloads.sourceforge.net/courier/courier-authlib-0.62.2.tar.bz2
wget http://prdownloads.sourceforge.net/courier/courier-imap-4.5.0.tar.bz2
wget http://prdownloads.sourceforge.net/courier/maildrop-2.1.0.tar.bz2
Now (still in /tmp) we can build courier-authlib:
sudo rpmbuild -ta courier-authlib-0.62.2.tar.bz2
After the build process, the rpm packages can be found in $HOME/rpm/RPMS/x86_64 ($HOME/rpm/RPMS/i386 if you are on an i386 system):
cd $HOME/rpm/RPMS/x86_64
The command
ls -l
shows you the available rpm packages:
[compileuser@server1 x86_64]$ ls -l
total 608
-rw-r--r-- 1 root root 139745 May 25 14:52 courier-authlib-0.62.2-1.x86_64.rpm
-rw-r--r-- 1 root root 328419 May 25 14:52 courier-authlib-debuginfo-0.62.2-1.x86_64.rpm
-rw-r--r-- 1 root root 35322 May 25 14:52 courier-authlib-devel-0.62.2-1.x86_64.rpm
-rw-r--r-- 1 root root 18310 May 25 14:52 courier-authlib-ldap-0.62.2-1.x86_64.rpm
-rw-r--r-- 1 root root 14501 May 25 14:52 courier-authlib-mysql-0.62.2-1.x86_64.rpm
-rw-r--r-- 1 root root 13714 May 25 14:52 courier-authlib-pgsql-0.62.2-1.x86_64.rpm
-rw-r--r-- 1 root root 8358 May 25 14:52 courier-authlib-pipe-0.62.2-1.x86_64.rpm
-rw-r--r-- 1 root root 35287 May 25 14:52 courier-authlib-userdb-0.62.2-1.x86_64.rpm
[compileuser@server1 x86_64]$
Select the ones you want to install, and install them like this:
sudo rpm -ivh courier-authlib-0.62.2-1.x86_64.rpm courier-authlib-mysql-0.62.2-1.x86_64.rpm courier-authlib-devel-0.62.2-1.x86_64.rpm
Now we go back to the /tmp directory and run rpmbuild again, this time without sudo, otherwise the compilation will fail because it was run as root:
cd /tmp
rpmbuild -ta courier-imap-4.5.0.tar.bz2
After the build process, the rpm packages can be found in $HOME/rpm/RPMS/x86_64 ($HOME/rpm/RPMS/i386 if you are on an i386 system):
cd $HOME/rpm/RPMS/x86_64
The command
ls -l
shows you the available rpm packages:
[compileuser@server1 x86_64]$ ls -l
total 1924
-rw-r--r-- 1 root root 139745 May 25 14:52 courier-authlib-0.62.2-1.x86_64.rpm

-rw-r--r-- 1 root root 35287 May 25 14:52 courier-authlib-userdb-0.62.2-1.x86_64.rpm
-rw-r--r-- 1 compileuser compileuser 397262 May 25 15:04 courier-imap-4.5.0-3.x86_64.rpm
-rw-r--r-- 1 compileuser compileuser 940108 May 25 15:04 courier-imap-debuginfo-4.5.0-3.x86_64.rpm
[compileuser@server1 x86_64]$
You can install courier-imap like this:
sudo rpm -ivh courier-imap-4.5.0-3.x86_64.rpm
Now we go back to the /tmp directory and run rpmbuild again, this time to build a maildrop package:
cd /tmp
sudo rpmbuild -ta maildrop-2.1.0.tar.bz2
After the build process, the rpm packages can be found in $HOME/rpm/RPMS/x86_64 ($HOME/rpm/RPMS/i386 if you are on an i386 system):
cd $HOME/rpm/RPMS/x86_64
The command
ls -l
shows you the available rpm packages:
[compileuser@server1 x86_64]$ ls -l
total 3188
-rw-r--r-- 1 root root 139745 May 25 14:52 courier-authlib-0.62.2-1.x86_64.rpm
-rw-r--r-- 1 root root 328419 May 25 14:52 courier-authlib-debuginfo-0.62.2-1.x86_64.rpm
-rw-r--r-- 1 root root 35322 May 25 14:52 courier-authlib-devel-0.62.2-1.x86_64.rpm
-rw-r--r-- 1 root root 18310 May 25 14:52 courier-authlib-ldap-0.62.2-1.x86_64.rpm
-rw-r--r-- 1 root root 14501 May 25 14:52 courier-authlib-mysql-0.62.2-1.x86_64.rpm
-rw-r--r-- 1 root root 13714 May 25 14:52 courier-authlib-pgsql-0.62.2-1.x86_64.rpm
-rw-r--r-- 1 root root 8358 May 25 14:52 courier-authlib-pipe-0.62.2-1.x86_64.rpm
-rw-r--r-- 1 root root 35287 May 25 14:52 courier-authlib-userdb-0.62.2-1.x86_64.rpm
-rw-r--r-- 1 compileuser compileuser 397262 May 25 15:04 courier-imap-4.5.0-3.x86_64.rpm
-rw-r--r-- 1 compileuser compileuser 940108 May 25 15:04 courier-imap-debuginfo-4.5.0-3.x86_64.rpm
-rw-r--r-- 1 root root 299343 May 25 15:13 maildrop-2.1.0-3.x86_64.rpm
-rw-r--r-- 1 root root 770389 May 25 15:13 maildrop-debuginfo-2.1.0-3.x86_64.rpm

-rw-r--r-- 1 root root 63937 May 25 15:13 maildrop-man-2.1.0-3.x86_64.rpm
[compileuser@server1 x86_64]$
You can now install maildrop like this:
sudo rpm -ivh maildrop-2.1.0-3.x86_64.rpm
After you have compiled and installed all needed packages, you can become root again by typing
exit
11 Apply Quota Patch To Postfix
We have to get the Postfix source rpm, patch it with the quota patch, build a new Postfix rpm package and install it.
cd /usr/src
wget http://ftp-stud.fht-esslingen.de/pub/Mirrors/centos/5.3/os/SRPMS/postfix-2.3.3-2.1.el5_2.src.rpm
rpm -ivh postfix-2.3.3-2.1.el5_2.src.rpm
The last command will show some warnings that you can ignore:
warning: user mockbuild does not exist - using root
warning: group mockbuild does not exist - using root
cd /usr/src/redhat/SOURCES
wget http://vda.sourceforge.net/VDA/postfix-2.3.3-vda.patch.gz
gunzip postfix-2.3.3-vda.patch.gz
cd /usr/src/redhat/SPECS/
Now we must edit the file postfix.spec:
vi postfix.spec
Change %define MYSQL 0 to %define MYSQL 1, add Patch0: postfix-2.3.3-vda.patch to the # Patches stanza, and finally add %patch0 -p1 -b .vda to the %setup -q stanza:
[...] %define MYSQL 1 [...] # Patches Patch0: postfix-2.3.3-vda.patch Patch1: postfix-2.1.1-config.patch Patch3: postfix-alternatives.patch Patch6: postfix-2.1.1-obsolete.patch Patch7: postfix-2.1.5-aliases.patch Patch8: postfix-large-fs.patch Patch9: postfix-2.2.5-cyrus.patch Patch10: postfix-CVE-2008-2936.patch [...] %setup -q # Apply obligatory patches %patch0 -p1 -b .vda %patch1 -p1 -b .config %patch3 -p1 -b .alternatives %patch6 -p1 -b .obsolete %patch7 -p1 -b .aliases %patch8 -p1 -b .large-fs %patch9 -p1 -b .cyrus %patch10 -p1 -b .CVE-2008-2936 [...] |
Then we build our new Postfix rpm package with quota and MySQL support:
rpmbuild -ba postfix.spec
Our Postfix rpm package is created in /usr/src/redhat/RPMS/x86_64 (/usr/src/redhat/RPMS/i386 if you are on an i386 system), so we go there:
cd /usr/src/redhat/RPMS/x86_64
The command
ls -l
shows you the available packages:
[root@server1 x86_64]# ls -l
total 11732
-rw-r--r-- 1 root root 3940144 May 25 15:19 postfix-2.3.3-2.1.x86_64.rpm
-rw-r--r-- 1 root root 7999302 May 25 15:20 postfix-debuginfo-2.3.3-2.1.x86_64.rpm
-rw-r--r-- 1 root root 49760 May 25 15:19 postfix-pflogsumm-2.3.3-2.1.x86_64.rpm
[root@server1 x86_64]#
Pick the Postfix package and install it like this:
rpm -ivh postfix-2.3.3-2.1.x86_64.rpm
Then turn off Sendmail and start Postfix, saslauthd, and courier-authlib:
chkconfig --levels 235 courier-authlib on
/etc/init.d/courier-authlib start
chkconfig --levels 235 sendmail off
chkconfig --levels 235 postfix on
chkconfig --levels 235 saslauthd on
/etc/init.d/sendmail stop
/etc/init.d/postfix start
/etc/init.d/saslauthd start
12 Configure Courier
Now we create the system startup links for courier-imap:
chkconfig --levels 235 courier-imap on
/etc/init.d/courier-authlib restart
/etc/init.d/courier-imap restart
When courier-imap is started for the first time, it automatically creates the certificate files /usr/lib/courier-imap/share/imapd.pem and /usr/lib/courier-imap/share/pop3d.pem from the /usr/lib/courier-imap/etc/imapd.cnf and /usr/lib/courier-imap/etc/pop3d.cnf files. Because the .cnf files contain the line CN=localhost, but our server is named server1.example.com, the certificates might cause problems when you use TLS connections. To solve this, we delete both certificates...
cd /usr/lib/courier-imap/share/
rm -f imapd.pem
rm -f pop3d.pem
... and replace the CN=localhost lines in /usr/lib/courier-imap/etc/imapd.cnf and /usr/lib/courier-imap/etc/pop3d.cnf with CN=server1.example.com:
vi /usr/lib/courier-imap/etc/imapd.cnf
[...] CN=server1.example.com [...] |
vi /usr/lib/courier-imap/etc/pop3d.cnf
[...] CN=server1.example.com [...] |
Then we recreate both certificates...
./mkimapdcert
./mkpop3dcert
... and restart courier-authlib and courier-imap:
/etc/init.d/courier-authlib restart
/etc/init.d/courier-imap restart
13 Install Getmail
Getmail can be installed as follows:
yum install getmail
