OpenDKIM Postfix & Centos 5.5

Installing OpenDKIM from source on CentOS 5.5 to sign and verify emails with Postfix

This guide assumes you have CentOS 5.5 installed, a  working Postfix configuration and that you would like to sign mail for more than one domain. It was carried out with the following software versions:

• Postfix 2.3.3
• OpenDKIM 2.0.4
• Sendmail (sources) 8.13.8
• OpenSSL 0.9.8e

Important links:

• OpenDKIM
• Sendmail DKIM tools

Install other necessary software

# yum install sendmail-devel
# yum install openssl-devel

If you want to know exactly where the files belonging to a package are (OpenDKIM’s compiler should find them automatically):

# rpm -ql sendmail-devel
/usr/include/libmilter
/usr/include/libmilter/mfapi.h
/usr/include/libmilter/mfdef.h
/usr/lib/libmilter.a
/usr/lib/libsm.a
/usr/lib/libsmutil.a
