Note: I barely know what I'm doing here, as such this may be incredibly obvious, but I wasn't able to find what I was after on Google.
Running CentOS 6.7
Yesterday I followed this guide to set up opendkim on my server, and as far as I can tell it is working.
This guide told me to get the opendkim package via
tar zxvf opendkim-2.4.2.tar.gz cd opendkim-2.4.2 ./configure --sysconfdir=/etc --prefix=/usr/local --localstatedir=/var make make install
I've since found out this is not the latest version (I know I should have checked that first -__-). I found an updated version of the guide showing this can now be installed via
yum install opendkim.
I would like to move to using that method, but I don't know enough about this stuff to know if that will overwrite things cleanly - or even at all.
What's the safest/best way to install opendkim with yum while removing/overwriting the manual installation (while keeping my configuration ideally - but that can be redone if necessary)
