OPENDKIM Filter reporting KeyTable entry for 'DOMAIN' corrupt and error loading key 'domain'

Installed OPENDKIM on Centos 6 running with Sendmail.
I seem to get inthe mail logs the following error message when I attempt to send a DKIM header out. Error message in mail log :-
Jan 24 16:18:04 mail-02 opendkim[6038]: KeyTable entry for 'extsmtp003' corrupt
Jan 24 16:18:04 mail-02 opendkim[6038]: r0OGI4p4006092: error loading key 'extsmtp003'
Jan 24 16:18:04 mail-02 sendmail[6092]: r0OGI4p4006092: Milter: data, reject=451 4.3.2 Please try again later

I have re-generated the key using opendkim-genkey as required and attempted to send a mail out that matches the KeyTable file i.e. the FROM address.  I have modified the "KeyFile" to look at a simple txt file with just some random txt in and it comes up with the same error message. So I am pretty sure its not the PRIVATE key but possibly permissions.
Permission are set as  :-
-rwxrwxrwx  1 opendkim opendkim   51 Jan 24 16:16 KeyTable
drwxrwxrwx  2 opendkim opendkim 4096 Jan 24 16:02 private
-rw-r--r--  1 root     root      115 Jan 15 15:44 returnpath.php
-rwxrwxrwx  1 opendkim opendkim   25 Jan 24 14:53 SigningTable
-rwxrwxrwx  1 opendkim opendkim   75 Jan 22 13:22 TrustedHosts

Contents if the keytable are as below :-

more  Key*

Appreciate if I am missing something .

Your syntax on the KeyTable file is wrong. Should read something like:


Your permissions are okay.

I have changed the KeyTable to :-
[root@mail-02 dkim]# more Key*

Attempt to send a mail and now I get the following message in the maillog :-
signing table references unknown key 'extsmtp003'
Jan 25 09:09:56 mail-02 sendmail[19627]: r0P99usf019627: Milter: data, reject=451 4.3.2 Please try again later

Slightly different error now.
Try replacing your KeyTable entry to:

chances are you followed the guides online to the tee and used 'default' as the selector
