OpenDKIM Howto
cd /etc/opendkim/keys
The 'selector' you choose here does not have to be the actual selector used in DNS. It is just the name used for storing the .txt and .private files
opendkim-genkey -s somename -d domain.name
Make sure the key ends up in /etc/opendkim/keys and is readable for user opendkim
SigningTable
- somename is the first field in Keytable
*@domain.name somename
KeyTable
Here the name of the selector is the one you publish in dns
somename domain.name:selectorname:/path/to/somename.private
Checking
opendkim-testkey -v
This will try to fetch the key published in DNS, so "record not found" means DNS record not found.
FAQ

In opendkim.conf use:
refile:/etc/opendkim/SigningTable
opendkim-testkey key not secure
Probably means you have no DNSSEC
