Designing Organization Configuration to Meet Routing Requirements
33
You can configure a Receive connector on a per-server scope only. Thus,
if you want to have many servers receive messages, you need to configure
every server.
Receive connectors have configuration limits that you can set, such as number of active
connection, maximum message size, or maximum recipients per message. You also can set the
type of authentication required to send a message. What does this have to do with planning?
Well, you should configure Receive connectors at every Hub Transport server that serves an
external inbound connection. Also, you should have dedicated Receive connectors for your
applications that want to send messages so that you understand how many applications send
messages to your system.
Foreign Connectors
A Foreign connector does not use the SMTP protocol for communication. Third-party Short
Message Service (SMS) gateways or fax gateways are examples.
To be able to communicate with these third-party systems, the connector uses a Drop direc-
tory on the Hub Transport server to send messages to the foreign gateway servers. Foreign
gateway servers can send messages to Exchange Server 2007 by using the Replay directory.
Every foreign connector has an address space assigned to it that includes the following elements:
Connector Scope: What Hub Transport servers can use the connector
AddressSpaceType: For example, fax or SMTP
AddressSpace: An valid address space for the AddressSpaceType
AddressSpaceCost: Routing costs
Using Direct Connectors to Business Partners
In my company we work very closely with a couple of other companies; we also have a direct
network link connecting us all together. This link is used to exchange confidential data as well
as access to certain systems.
As these links normally are utilized only during specific times of the day, it’s a big benefit to
configure Send and Receive connectors using these links. They have their own SMTP address
space, and messages use only the direct connection.
Not only does my company save the traffic that would be generated by all the messages first
being sent to the Internet and then being received by the target again, but we also improve
security as messages are not routed over the Internet.
