Plesk 12 Centos 6 install OpenDKIM

Plesk opendkim

Today i fought with Plesk 12 and Centos 6 to install OpenDKIM with DOMAIN KEY and SPF.

For domain key and spf is simple, just for each domain on plesk directly active it in the setting mail.

OpenDKIM is a service that must be installed on centos directly.
Let’s start!

Install opendkim and opendkim tools:

yum update
wget -P /tmp http://mirror.pnl.gov/epel/6/i386/epel-release-6-8.noarch.rpm
rpm -Uvh /tmp/epel-release-6-8.noarch.rpm
rm -f /tmp/epel-release-6-8.noarch.rpm
yum install opendkim opendkim-tools

Now we must to create the directory that can be used than with opendkim for keys generation

mkdir -pv /etc/opendkim/keys
chown -Rv opendkim:opendkim /etc/opendkim
chmod go-rwx /etc/opendkim/*

touch /etc/opendkim/KeyTable
touch /etc/opendkim/SigningTable
touch /etc/opendkim/TrustedHosts

Then to simple generate the key and assign the domain to trusted host and signing table, create a simple script.

Create the file:

/opt/generatedkim.sh

and put in it:


#!/bin/bash
# /opt/generatedkim.sh
die () {
echo >&2 "$@"
exit 1
}

[ “$#” -eq 1 ] || die “1 argument required, $# provided, domain required, ex: ./script example.com”

cwd=pwd
opendkim=”/etc/opendkim”
location=”$opendkim/keys/$1″
[ -d “$location” ] && die “There is already a directory in the folder, delete folder if you want to create a new one”

mkdir -p “$location”
cd “$location”
opendkim-genkey -d $1 -s mail
chown opendkim:opendkim *
chown opendkim:opendkim “$location”
chmod u=rw,go-rwx *
echo “$1 $1:mail:$location/mail.private” >> “$opendkim/KeyTable”
echo “*@$1 $1” >> “$opendkim/SigningTable”
echo “$1” >> “$opendkim/TrustedHosts”
echo “mail.$1” >> “$opendkim/TrustedHosts”
echo
echo “Put this in the DNS ZONE for domain: $1”
echo
cat “$location/mail.txt”
echo
cd “$cwd”

Now we must use it to generate the domain keys and dns record:


/opt/generatedkim.sh test.de

Put this in the DNS ZONE for domain: test.de

mail._domainkey IN TXT “v=DKIM1; k=rsa; p=MIGfMA0GCSqGSIb3DQEBAQUAA4GNADCBiQKBgQDPzE0GmvFwAQsgcFzopy4zMNWUbL6JM5XIyjBy3bUnANI5axeb
/Lw/GBjUoSFLEiO80Tt8m3A5YrBKcodRQQURYiW6/
YtElhLupHyfcxQhfNLU4z9JUOJKPjcpMZCj0Xv873QgVOl+7U605JdBHSPOx4ybBZwDq68cw9YFYRPmEwIDAQAB” ; —– DKIM key mail for test.de

Create the record dns as the script put out on your domain dns zone.

Remember that if you restart the server you must go up the service of opendkim!!
