Hello Everybody

I have recently configured DKIM in CentOS 5.3.
Using DKIM-milter for Sendmail to Sign and transfer e-mails.

DKIM correctly Signs mails that originate from the mail server.
But refuses to Sign mails that are sent from one of our Remote Server.
The remote server uses this mail server to relay mails.

I have added the remote server's IP in /etc/mail/dkim/trusted-hosts.
Configured /etc/mail/dkim/trusted-hosts as InternalHosts list in /etc/dkim-milter.conf
/etc/mail/dkim/trusted-hosts is having correct permissions and is accessible from dkim-milter.
I have provided below the DKIM errors i received in /var/log/maillog.

Code:
