About connecting Microsoft Exchange email services

You can integrate Perception Point X‑Ray with Microsoft Exchange. This enables Perception Point X‑Ray to protect all incoming mail to Microsoft Exchange. [Refers to Microsoft Exchange On-Premises]

  • Integration with Microsoft Exchange requires an MX record change.

  • With the "Exchange" integration method, remediation is not available.

  • With the "Exchange" integration method, Perception Point X‑Ray will protect all users in the account - it is not possible to specify groups, email accounts, or users to protect.

  • With the "Exchange" integration method, scanning of outbound emails is not available.

  • The "Exchange" integration method can be used to protect accounts that have Exchange Online Kiosk licenses.

Perception Point X‑Ray scans email messages up to a maximum size of 40 MB [including attachments]. Larger email messages are not scanned by Perception Point X‑Ray, and will be delivered to the specified recipients.

Note:

  • Due to external technical limitations, the 40 MB limitation can't be increased.

  • We recommend that you limit receiving email attachments up to 30 MB in size. Files that are larger than 30 MB should be shared using a different file sharing service, such as Microsoft OneDrive or Google Drive.

Onboarding process

  • Customer onboarding entails adding the domain name and verifying a TXT record in the system.

  • During the onboarding process, you'll need to add the next hop (MX record) so that Perception Point X‑Ray knows where to deliver the email after scanning.

Email flow overview

  • All inbound emails are directed straight to the Perception Point X‑Ray scanner upon arrival.

Scanning and response

  • Clean: Clean emails verified by Perception Point X‑Ray are sent back to the configured server (Next SMTP).

  • Spam: Emails identified as spam by Perception Point X‑Ray are sent back to the configured server (Next SMTP).

    • For servers utilizing header-based rules to redirect spam to the Junk Email folder, you can append the "X-PERCEPTION-POINT-SPAM: FAIL" header.

    • In Exchange 2013/2019, this can be accomplished through transport rules.

  • Malicious: Emails identified as malicious are blocked and are not forwarded to the next server.

Note: With the "Exchange" integration method, remediation is not available. This means that if an email was initially assigned a clean verdict, which was later changed to malicious, the email will not be removed from the user's Inbox.
