I only have four non local users that are allowed to relay. These just have entries in smtpauth.tab. They have their mta connect via port 465 rather than port 25 as at least one has their ISP block port 25. I can't remember any other requirement (other than setting up SSL) and it's worked ok. I've still not worked out if you want mail coming in via postini to be allowed to be relayed or if postini is just an external filter for scanning some of your incoming mail. If the latter, I can't see why it should need to be treated different to any other incoming email. However you've mentioned putting an entry for postini in smtprelay.tab which would indicate that you intend it is allowed to be relayed. I can't see how that can be done securely though without authentication.
