Tengo a la mano el artículo para bloquearlo, mas no para liberar el relay,

Imagino que solo hay que cambiar el paso de filtrado.

Configure the Exchange Server to Block Open SMTP Relaying

There are two Exchange server components that allow SMTP relaying to be
turned on or off: the Default SMTP Virtual Server and the SmallBusiness SMTP
Connector.

Set the properties on the Default SMTP Virtual Server.

Click Start, click Programs, click Microsoft Exchange, and then click System
Manager. Expand Servers, expand Servername, expand Protocols, and then
expand SMTP.

If the server is an upgrade from Small Business Server 4.x, expand
Administrative Groups, expand Servername, expand Servers, expand Servername,
expand Protocols, expand SMTP.

Right-click the Default SMTP Virtual Server and select Properties. Click the
Access tab. Click the Relay... button at the bottom. The default settings
block open relay. The default settings are as follows:

Select Only the list below.

Make sure that the Computers dialog box shows Access Granted to the Internal
IP address of the Small Business Server 2000 computer and to the external IP
address (if the server has more than one network card.) Make sure that Allow
all computers which successfully authenticate to relay, regardless of the
list above is selected. Set the Default SMTP Virtual Server configuration
for relaying as indicated, which restores its settings to their defaults.
Set the properties for the SmallBusiness SMTP Connector.

In the Exchange System Manager, expand Connectors, and then locate the
SmallBusiness SMTP Connector.

If the server is an upgrade from Small Business Server 4.x, expand
Administrative Groups, expand Servername, and then expand Connectors.

NOTE: The SmallBusiness SMTP Connector is created when you run the Small
Business Server 2000 Internet Connection Wizard. If you have created an SMTP
connector manually, it may not be called SmallBusiness SMTP connector. Also
note that the SMTP connector is not required for external mail flow. The
absence of a connector may not indicate a problem. If you do not have an
SMTP connector under Connectors, go to the "Clean Up the Exchange Server's
SMTP Queues" section of this article. Right-click the SmallBusiness SMTP
connector (or on the connector name you manually created) and then click
Properties. Click the Address Space tab. The default settings (when this
connector is created by means of the Small Business Server 2000 Internet
Connection Wizard) block open relay. The default settings are:

Address Space -Type: SMTP

-Address: *

-Cost: 1



The Connector Scope is Entire Organization.

Allow messages to be routed to these domains is cleared (not selected).
Configure the SMTP Connector as indicated to restore its settings to their
default values.
