Email Domains DNS DKIM setup

I am setting up dkim for my server - which sends emails from hosted websites (postfix). Just want to get some input before I attempt to deploy.

Example server host name is xxxx.yyyy.com

Let say I have 4 domains hosted on the server
aaa.com
bbb.com
ccc.com
ddd.com

I have SPF records (xxx.yyy.com included) setup for each domain in their DNS

I also have DMARC and DKIM records setup for the domains for the main outside mail servers (some are google and some are business 365).

Do I just use the centminmod script to create a DKIM key / record for server xxx.yyy.com and then setup the created DKIM record in the DNS of each of the domains? Nothing else to do?

Thanks

Thanks eva2000

I followed the instructions and ran ./opendkim.sh and I got two errors:

• http://yum.mariadb.org/10.1/centos7-amd64/repodata/repomd.xml: [Errno 14] HTTP Error 404 - Not Found

• cp: cannot stat ‘/etc/opendkim.conf’: No such file or directory

Looks like I also have to fix a repository problem.

What do I need to do to get this script to run?

I am on centos 7 and cmupdate shows latest version.
MariaDB version: 10.1.48-MariaDB

 

124.00stable

 

Code:

[mariadb]
name = MariaDB
baseurl = http://yum.mariadb.org/10.1/centos7-amd64
gpgkey=https://yum.mariadb.org/RPM-GPG-KEY-MariaDB
gpgcheck=1
exclude=MariaDB-Galera-server

Regarding "centmin.sh menu once and exit", do you mean run centmin.sh and then just enter "24" to immediately exit out of the script?

If so I tried that and the same error.

Updated to 130.00beta01 and ran centmin.sh and then exited with option 24.

Still the same problem when I run addons/opendkim.sh again.

Code:

http://yum.mariadb.org/10.1/centos7-amd64/repodata/repomd.xml: [Errno 14] HTTP Error 404 - Not Found

 

yes, it works now!
Thanks a lot eva2000, much appreciated.
