Any user that authenticates is allowed to relay, so I'd think that's the part you need to protect. One option would be to disallow ESMTP authentication entirely on whatever server the users are using, and to set up a separate mail relay server where you can filter authentication to only specific whitelisted users. Another would be to allow authentication, but use a courierfilter to check the sender and recipients and apply a local policy to allow or deny relaying messages. ------------------------------------------------------------------------------ Site24x7 APM Insight: Get Deep Visibility into Application Performance APM + Mobile APM + RUM: Monitor 3 App instances at just $35/Month Monitor end-to-end web transactions and take corrective actions now Troubleshoot faster and improve end-user experience.
