Symantec Messaging Gateway version 9.0 and above do not use the postmaster mailbox for messages addressed to unresolved recipients
Last Updated September 27, 2011
Starting with Symantec Messaging Gateway (formerly Symantec Brightmail Gateway) version 9.0, spam messages addressed to unresolved recipients are no longer stored in the postmaster mailbox when viewing the Spam Message Quarantine. So, typing the word "postmaster" in the "To" field when the filters are shown yields the same behavior as leaving the "To" field blank: all spam messages, addressed to both resolved and unresolved recipients are shown.
In SMG versions 8.0.3 and below, typing the word "postmaster" in the "To" field when the filters are shown will produce the list of spam messages addressed to unresolved recipients only.
However, the administration guide and the online help for versions 9.0 and above still describe the old behavior as seen in versions 8.0.3 and below.
This is by design that is changed between SMG versions 8.0.3 and 9.0. If a recipient cannot be resolved by using the configured LDAP source for an SMG appliance, the appliance will no longer save the quarantined spam message addressed to that unresolved recipient in the postmaster's mailbox. It will save the message in the Spam Message Quarantine with the original "envelope rcpt to" as the recipient's mailbox instead of the "postmaster" mailbox, so typing "postmaster" in the "To" field when the filters are shown will display all quarantined spam messages addressed to both resolved and unresolved recipients.
Symantec is aware of the documentation issue and is looking for ways to resolve it in the future versions of the SMG product.
Note: Spam Message Quarantine filters are available here: Spam->Quarantine->Email Spam, on the "Spam Message Quarantine" page, click on the "Show filters" button.
