Scrollout can't deliver inbound emails

basically when I send emails inbound to my mail server it should be going through a mail gateway to get scanned for spam - I'm in the process of setting it up.

The message I get is as follows:

Delivery to the following recipient failed permanently:
 
     Ryan@vidyagam.es
 
Technical details of permanent failure:
Google tried to deliver your message, but it was rejected by the server for the recipient domain vidyagam.es by maridia.vidyagam.es. [92.222.14.141].
 
The error that the other server returned was:
550-5.1.1 <Ryan@vidyagam.es>: Recipient address rejected: undeliverable address: host vidyagam.es[92.222.17.211] said: 550 5.7.1 <Ryan@vidyagam.es>: Recipient address rejected: Please see http://www.openspf.net/Why?s=mfrom;id=root%40vidyagam.es;ip=92.222.14.141;r=vps140986.ovh.net (in reply to RCPT TO command)
550 5.1.1 For assistance, see https://vidyagam.es or contact +447904971195. Please provide the following information in your problem report: Time: (Feb 18 10:58:24), Client: (209.85.217.182), Server: (maridia.vidyagam.es).

The SPF error isn't really helpful either.

vps140986.ovh.net rejected a message that claimed an envelope sender address of root@vidyagam.es.

vps140986.ovh.net received a message from 141.ip-92-222-14.eu (92.222.14.141) that claimed an envelope sender address of root@vidyagam.es.

The domain vidyagam.es has authorized 141.ip-92-222-14.eu (92.222.14.141) to send mail on its behalf, so the message should have been accepted. It is impossible for us to say why it was rejected.
What should I do?

If the problem persists, contact the vidyagam.es postmaster.

So if anyone has any experience in this and can help me out I'd much appreciate it. I can't seem to pinpoint the error, if it's with the Scrollout box, the Postfix config or something else.
