Exchange 2010 rejects gmail

Hi,

In the last weeks 2 of our sbs 2011 server (with exchange 2010) rejecting emails sent from google.

The messages are rejected with the following error:

Delivery to the following recipient failed permanently:

    mail@[recipientdomain]

Technical details of permanent failure:
Google tried to deliver your message, but it was rejected by the server for the recipient domain [recipientdomain] by [exchangeserver].

The error that the other server returned was:
554 5.7.1 <mail@[recipientdomain]>: Relay access denied

The thing is, that the sender only gets blocked when sending from the gmail servers. When we test sending with a gmail address from a mail client that uses the smtp of a local ISP, than the message gets deliverd.

Thanks in advance.

Regards

Do you have an SPF record in your domain's public DNS?

If not, you need one.
