server where you create the post office directory structure can be in the same tree as the Post Office
object or in another tree.
Databases and directories in the post office are updated as messages are sent. Because the POA
typically makes these updates, we recommend that you place the post office directory on a server
that can be easily accessed by the POA and, depending on configuration, the MTA. Users typically
need a TCP/IP connection to the POA in order to access their mailboxes.
When you are planning the post office directory location and which users will belong to the post
office, consider the following:
Post Office Directory Space Requirements:
You need a minimum of 50 MB for each user.
Because the message store can require considerable disk space, we recommend you allow each
user at least 200 MB of storage space. You should also take into consideration the size of
attachments, and your archive and delete policies. If message attachments are large and you are
not planning to require users to archive or delete old messages, allow more storage. If you are
creating libraries you need even more storage, depending on the size and number of documents.
For details about managing post office disk space, see
Section 12.3, “Managing Disk Space
Usage in the Post Office,” on page 182
.
Network Access by the POA:
The POA must have direct network access (mapped drive or
file system mount) to the post office directory so that it can write to user databases (
user
xxx
.db
)
and message databases (
msg
nnn
.db
). This issue is discussed in detail in
Section 11.2.6,
“Deciding Where to Install the Agent Software,” on page 161
.
Security from User Access:
Users typically access their mailboxes through a TCP/IP
connection to the POA. Therefore, users do not need access to the post office directory. You
should create it in a location you can easily secure; otherwise, you could have files
inadvertently moved or deleted.
Choose an empty directory for the new post office. If you want, the directory can reflect the name of
the post office, for example research for the Research post office. Use the following platform-
specific conventions:
Choose the name and path carefully. After the post office directory is created, it is difficult to rename
it. If the directory you specify does not exist, it is created when you create the post office. Do not
create the post office directory under another domain or post office directory.
11.2.6 Deciding Where to Install the Agent Software
You must run a new instance of the POA for each new post office. To review the functions of the
POA for the post office, see
Section 35.5, “Role of the Post Office Agent,” on page 469
. For
NetWare:
Use a maximum of 8 characters
Linux:
Use only lowercase characters
Windows:
No limitations.
