Here we describe how to add domainkeys and SPF (Sender Policy Framework) records on cPanel Servers. Whenever you create a domain on cPanel server using WHM, it wont add domainkeys and SPF records for particular domains. To add domainkeys and SPF records please use following steps.
Please note on cPanel servers most of the work is done using cpanel username which then reflect setting on particular domains. If you have several domains / sub domains under one username, it will add domainkeys and SPF records for all domains / subdomains.
The cPanel developers indicated that DKIM auth will be a feature in 11.32 version.
cPanel does not recommend or provide support for some of the changes this tutorial will ask you to make. As usual, make these changes at your own risk.
There are scripts in /usr/local/cpanel/bin that can install these on a per-user basis:
/usr/local/cpanel/bin/dkim_keys_install <username>
/usr/local/cpanel/bin/spf_installer <username>
If you wish to add DomainKeys and SPF for all Cpanel users on your server, execute following command.
for user in `ls -A /var/cpanel/users` ; do
/usr/local/cpanel/bin/dkim_keys_install $user &&
/usr/local/cpanel/bin/spf_installer $user ; done
