Mail Security for Microsoft Exchange

Issue/Introduction

When attempting to release an email addressed to an external recipient from the Symantec Mail Security for Microsoft Exchange (SMSMSE) quarantine the item is never received by the recipient. If the quarantine view is refreshed, the item once again appears in the quarantine with the same quarantine ID and timestamp as prior to attempting to release.

550 5.7.1 Unable to relay

If a debugview log of the quarantine release attempt is generated per 'How to Obtain Debug Logs for Symantec Mail Security for Microsoft Exchange (SMSMSE)' the following error is observed:

Cause

The Original Recipient is an external recipient.

The Exchange server defined as the SMTP Server in SMSMSE Console under Monitors -> Notification settings does not accept messages address to external recipients via the SMTP protocol.
 

Resolution

In order to allow SMSMSE to release to external recipients, we would recommend configuring a new receive connector whose scope includes only this Exchange server(IP), and allow relaying for that receive connector.

For details on how to accomplish this process, see '​Allow Anonymous Relay on a Receive Connector'
