This topic provides information about setting
up community IDs for use with ELA. Community IDs are used to restrict
message sending and receiving among groups of subscribers.
You must set up the following community IDs for ELA:
- You must set up a Community ID for the enhanced-list mailbox
community. Give that community permission to send to all other
communities (except the shadow mailbox community).
- You must set up a shadow mailbox Community ID. The shadow mailbox
Community ID is administered so that messages can be sent to any
community, but messages cannot be received from any other community.
- If you choose to restrict access to ELA usage, you can also
set up a special subscriber community and then administer that
community to send to all communities except the shadow mailbox
community. Place only those subscribers to whom you give permission
to use the enhanced lists into this special community. All other
subscribers must be administered to belong to a community restricted
from sending messages to the enhanced-list mailbox community.
Before you set up the community IDs for ELA,
use the display system-parameters sending restrictions command
in messaging administration and verify that there are at least two
communities that you can use for ELA (four communities are needed
if you are going to implement a special community for selected subscribers
with access to ELA mailboxes).
|
Note: If the messaging system
is networked with other messaging systems, all enhanced-list
mailbox community sending restrictions must be consistently
applied throughout the systems. Community ID numbers must
have the same meanings on all machines. Of particular importance
is that the shadow mailbox community must not be accessible
by any other community on any machine in the network.
See Setting up community sending restrictions
for a thorough description of community sending restrictions.

Setting up the ELA community
ID and shadow community ID
To set up the ELA Community ID and Shadow
Community ID:
- Start at the Messaging Administration main
menu and select:
Global Administration
Messaging Administration
The system displays the SSH
user authentication dialog box. Enter your login, for example, sa or vm,
in the User name field and your password in the Password
field. Click Login. The system then displays the Messaging
command prompt screen.
- At the enter command prompt,
enter change system-parameters sending-restrictions.
The system displays the Sending
restrictions screen. In the sample screen:
- Enhanced-list mailboxes are assigned Community 10. Community
10 has permission to send to all other communities (except the
shadow mailbox community). Community 10 can also receive messages
from all communities except Community 1.
- Community 1 is assigned to subscribers who cannot send messages
to enhanced lists. Community 1 cannot send to Community 10.
- A special subscriber community, Community 9, is administered
to send to all communities (except the shadow mailbox community).
Only subscribers you would like to have access to the enhanced
lists are placed into Community 9. All other subscribers are
assigned Community 1 and are not able to send a message to the
enhanced list mailbox.
- The shadow mailbox community ID is set as Community 11. The
shadow mailbox community ID in the sample is administered so
that messages can be sent to any community, but messages cannot
be received from any other community.
- Enter y in the Activate
Restrictions? field.
- If all subscribers are to have
access to enhanced lists, skip this step.
Otherwise, enter an r in the field
that corresponds to the intersection between the (recipient) ELA
Community ID and the (sender) community to which the unpriveleged
subscriber population belongs. This action prevents those who
do not have access to enhanced lists from sending a message to
an enhanced list.
- Enter an r in all (recipient
community) fields in the column that corresponds to the community
ID that you assigned to the shadow mailbox. This prevents messages
from being sent into the shadow mailbox.
- Press F3 (Enter) to save
the information in the system database.
The cursor returns to the command line,
and the system displays the following message:
Command Successfully Completed.
- Enter another administrative command at the
enter command prompt or click Return to Main.
|
Note: You must now use the
Edit Local Subscriber page to assign your subscribers either
to the community that does not have access to enhanced lists
or to the special community that does have access. If you
used your default subscriber community (Community 1) as
the community that does not have access, then you have to
administer only those selected individuals who will belong
to the new special community with access to enhanced lists.
