Email Spam Protection and Fraud Detection?

Question

Hi

This Microsoft article suggests that emails sent through Azure Communication Services are scanned for Malware, is this correct?

https://learn.microsoft.com/en-us/azure/communication-services/concepts/email/email-overview

"Email Spam Protection and Fraud Detection - Platform performs email hygiene for all messages and offers comprehensive email protection leveraging Microsoft Defender components by enabling the existing transport rules for detecting malware's, URL Blocking and Content Heuristic."

As the product articles do not suggest this, and there looks to be no Microsoft Defender option to configure policies, etc for this service. Are emails scanned?

Thanks

Phil

Hi @Phil Woolger

Yes, that's correct. Azure Communication Services provides email spam protection and fraud detection by performing email hygiene for all messages and leveraging Microsoft Defender components to detect malware, block URLs, and use content heuristics to detect suspicious content. You can read Azure security baseline for Azure Communication Services in this doc.

While there is no option to configure policies or settings for Microsoft Defender specifically for Azure Communication Services, the service leverages the existing transport rules for detecting malware and other threats. This means that the email messages sent through Azure Communication Services are scanned for malware and other threats before they are delivered to the recipient.

However, the platform doesn't guarantee that the emails that are sent through the platform lands in the customer's inbox. To proactively identify and avoid significant delivery problems, several reputation checks should be in place, including but not limited to:

• Ensuring a consistent and healthy percentage of successfully delivered emails over time.
• Analyzing specific details on email delivery failures and bounces.
• Monitoring spam and abuse reports.
• Maintaining a healthy contact list.
• Understanding user engagement and inbox placements.
• Understanding customer complaints and providing an easy opt-out process for unsubscribing.

To enable email logs and monitor your email delivery, follow the steps outlined in Azure Communication Services email logs Communication Service in Azure Communication Service.

Hope that helps.

Best,
