If you delete and then add back the same user in your message security service,
messages for that user are available in the Personal Archive only from the point at
which you add back the user.
General Message Flow for Message Security Service
Inbound email messages, and optionally outbound email messages, flow through
your message security service, which resides in a Postini data center. As the
message security service filters your incoming email, it quarantines suspicious
messages, and then delivers legitimate messages to your email server. The
following figure shows the message flow through your message security service.
With the addition of Message Archiving, you can archive messages for users in
one or more user organizations in your organization hierarchy.
