messages. This arrangement allows typical messages to be processed promptly, while delaying
large messages that exceed the specified size. The result is that large messages do not slow
down processing of typical messages.
5 Click OK .
6 To exit the Link Configuration Tool and save your changes, click File > Exit > Yes .
ConsoleOne then notifies the MTA to restart using the new message size limits.
If a user’s message is not sent out of the domain because of this restriction, the user receives an e-
mail message providing the following information:
Delivery disallowed - Transfer limit is nn MB
However, the message is delivered to recipients in the sender’s own domain.
There are additional ways to restrict the size of messages that users can send, as described in
Section 12.3.4, “Restricting the Size of Messages That Users Can Send,” on page 185 .
41.2.2 Enabling Live Remote
You can configure the MTA to redirect GroupWise Remote client requests to other MTAs and
POAs. The GroupWise client can establish a client/server connection to an MTA across the Internet,
eliminating the queuing and polling process used by earlier Remote clients. The result is
significantly improved performance for Remote client users.
To configure the MTA to redirect Remote client requests, add the /liveremote , /lrconn and /
lrwaitdata switches to the MTA startup file.
You can monitor the live remote connections from the MTA server console. See “Displaying Live
Remote Status” on page 653 .
As an alternative to live remote connections from outside your firewall, you could set up proxy
servers for the POAs, so that client users in Remote mode connect to their mailboxes through the
proxy servers rather than through MTAs. Full SSL security is provided through the proxy servers.
See
Section 36.3.1, “Securing Client/Server Access through a Proxy Server,” on page 496 .
41.2.3 Securing the Domain with SSL Connections to the MTA
Secure Sockets Layer (SSL) ensures secure communication between the MTA and other programs
by encrypting the complete communication flow between the programs. For background
information about SSL and how to set it up on your system, see
Chapter 71, “Encryption and
Certificates,” on page 1117 .
To configure the MTA to use SSL:
1 In ConsoleOne, browse to and right-click the MTA object, then click Properties .
2 Click GroupWise > Network Address to display the Network Address page.
