1）安装sendmail、openssl-devel包，安装opendkim需要依赖，加密用到

yum install sendmail-devel openssl-devel

2）安装opendkim

tar zxvf opendkim-2.4.2.tar.gz

cd opendkim-2.4.2
./configure --sysconfdir=/etc --prefix=/usr/local --localstatedir=/var
make
make install

3）添加用户及组

groupadd opendkim

useradd -r -g opendkim opendkim -G mail -s /sbin/nologin -d /var/run/opendkim -c "OpenDKIM"

4）创建目录，并授权

mkdir -p /var/run/opendkim 

chmod 700 /var/run/opendkim

mkdir -p /etc/opendkim/keys
chown -R opendkim:opendkim /etc/opendkim
chmod -R go-wrx /etc/opendkim/keys

5)拷贝到启动

cp /data/web/agx/opendkim-2.6.8/contrib/init/redhat/opendkim /etc/init.d/

chmod 755 /etc/init.d/opendkim

6）生成key

私钥：genrsa -out rsa.private 1024  

公钥：openssl rsa -in rsa.private -out rsa.public -pubout -outform PEM  writing RSA key  （需要添加到DNS记录中）

chown -R opendkim:opendkim /etc/opendkim/keys/xiaozhao.com/

把生成的私钥重命名为default，放到/etc/opendkim/keys/xiaozhao.com/下

问题：

1）[root@SJSWT46-80 libmilter]# /etc/init.d/opendkim start     

Starting OpenDKIM Milter: /usr/local/sbin/opendkim: error while loading shared libraries: libopendkim.so.7: cannot open shared object file: No such file or directory [FAILED]

解决：

[root@SJSWT46-80 libmilter]# echo "/usr/local/lib" >> /etc/ld.so.conf [root@SJSWT46-80 libmilter]# ldconfig

2）10.4.24.150

[root@YZSJHL24-150 opendkim-2.6.8]# make CDPATH="${ZSH_VERSION+.}:" && cd . && /bin/sh /data/web/dxm/opendkim/opendkim-2.6.8/build-aux/missing --run autoconf autom4te: cannot open /usr/local/share/autoconf/autom4te.cfg: No such file or directory make installmake: *** [configure] Error 1

3）10.3.23.52 没权限
