I have a problem with DKIM, I've generated the public and private keys by following the instructions here:- https://kb-beta.astaro.com/support/images/c/c8/301879.pdf
I have my private key within within Astaro and the logs seem to say each email is being signed as they pass through,

I sent an email to check-auth@verifier.port25.com for testing and it says my message isn't signed (obviosuly eample.co.uk isn't my domain - i have changed it for posting here):

A quick note: I created dkim.private and dkim.public, the public key in dns seems to be working, the private key is in Astaro including -----BEGIN RSA PRIVATE KEY----- -----END RSA PRIVATE KEY-----
and I have put the key selector as dkim
I have Exchange 2010 on my internal network and this routes all mail through my astaro box. Also, i don't use an external smart host.
What could be wrong, as I have set this up on two Astaro boxes now and am getting the same results.[:@]
Thanks in advance for any suggestions.
