Install Exim with DKIM and Domainkeys on DirectAdmin

Installing Exim on DirectAdmin makes my day today. I have to dig several sites in order to finish the installation. I think It will be better to document it here. I may need it again in the future, or perhaps you may need this when you need to compile Exim with DKIM and domainkeys on Centos.

First, compile and install the DKIM:

wget http://duncanthrax.net/exim-experimental/libdkim-1.0.16-tk.tar.gz

tar zxvf libdkim-1.0.16-tk.tar.gz

cd libdkim-1.0.16-tk

cd src

make

make install

cd ..

cp lib/libdkim.a /usr/lib

cp include/dkim.h /usr/include/

Compline and Install Domainkeys:

tar zxvf libdomainkeys-0.69.tar.gz

cd libdomainkeys-0.69

make

echo -lresolv > dns.lib

make

make install

cp *.h /usr/local/include/

cp *.a /usr/local/lib

Download Exim:

wget http://files.directadmin.com/services/all/exim/exim-4.69.tar.gz

tar xvzf exim-4.69.tar.gz

cd exim-4.69/Local

wget http://www.directadmin.com/Makefile

perl -pi -e 's/^EXTRALIBS/#EXTRALIBS/' Makefile

Edit the Makefile:

EXPERIMENTAL_DKIM=yes

CFLAGS  += -I/usr/include

LDFLAGS += -ldkim -lssl -lstdc++ -L/usr/lib

EXPERIMENTAL_DOMAINKEYS=yes

CFLAGS  += -I/usr/local/include

LDFLAGS += -ldomainkeys -L/usr/local/lib

#added April 9, 2008

HAVE_ICONV=yes

CFLAGS=-O -I/usr/local/include

EXTRALIBS_EXIM=-L/usr/local/lib -liconv

#end add

Compile and Install it:

cd ..

make

make install

Last job, you need to rename the compiled exim and restart:

cp -f /usr/sbin/exim-4.69-12 /usr/sbin/exim

/sbin/service restart exim

That's it, you have exim with domainkeys on DirectAdmin now.
