Dominic it would help if you posted your configuration. I suspect that you have the smtps service configured in master.cf. If anyone is using it, it should be only your own users, so errors from unrecognised ips will not be a problem and are probably not for any legitimate reason. If you don't need the smtps service, you should consider commenting it out completely in master.cf. John
