Setting Up Microsoft Exchange Journaling 23
The SMTP contact Postini Archive now appears in your user list in Active
Directory Users and Computers. For example:
Note: You can add a description, such as that shown in the figure, by editing the
contact.
Step 2. Set Up the Journal-Recipient Mailbox
Based on the number of journal-recipient mailboxes you need, which you
determined during your planning, you now need to set up the necessary journaling
mailbox stores and journal-recipient mailboxes on one or more Exchange
Servers. When setting up a journal-recipient mailbox, you must place it in a
mailbox store for which you do not plan to turn on journaling. (For information
about planning journal recipient mailboxes, see “Plan Your Journal-Recipient
Mailbox Deployment” on page 14.)
For greater security, Postini also recommends that you:
• Remove the journal-recipient mailbox from your Exchange Global Address
List, as a precaution to prevent users from sending email messages directly to
the archive.
• Set up a delivery restriction for the mailarchive user, to prevent anyone from
sending email messages directly to the journal-recipient mailbox.
To set up the journal-recipient mailbox:
1. Open Active Directory Users and Computers, and then connect to the
domain in which you want the journal user to reside.
