An Exchange 2010 server receive connector though apparently configured to accept e-mail from an ip is rejecting e-mail from every ip with the error
550 5.7.1 External client with ip address does not have permissions to submit to this server. I have compared with other internet receive connectors and it is set the same. Google seems to only bring up issues between hub and edge servers, this is a multi role single server setup. Thanks Graeme -- Good news everyone, you have just received an e-mail from me!
