Re: SMTP/ SmartHost for a dummy

Tech-Archive recommends: Speed Up your PC by fixing your registry

From a previous response:

SMTP Virtual Servers are "protocol listeners" - they receive inbound mail
(and in the context of Exchange Server 2003/2000, deliver outbound mail as
well).

SMTP Connectors are a bunch of settings that tell Exchange how to deliver
outbound mail for a particular address space (including * = all address
spaces that Exchange is neither authoritative for nor has an explicit SMTP
Connector for). SMTP Connectors use SMTP virtual servers as "bridgeheads" to
deliver outbound mail.

Whereas SMTP Virtual Servers are components of an Exchange server, SMTP (and
Routing Group) Connectors belong to a Routing Group (if scoped or restricted
to a Routing Group - you can setup a Connector so that it's available to all
Routing Groups = not scoped).

When any of the settings common to a SMTP Connector and a SMTP Virtual
Server conflict, settings of the Connector override that of the Virtual
Server for messages for the Connector's address space.

In Exchange Server 2007, the concept has been refined further to indicate
their purpose - they are now called Receive Connectors (**roughly
equivalent** to a SMTP Virtual Server) and Send Connectors.

I ran into a situation recently attempting to configure a SmartHost that
raised a couple of questions. With Exchange 2000, I enter the smart host info
on the SMTP virtual server, so I did the same with Exchange as part of
Win2003 SBS (does this make this an SBS question?). However, the messages
were not going through the smart host, and I finally figured out I had to
enter it in the (Small Business) SMTP Connector to get it to work.

Can someone please explain the relationship between the SMTP virtual server
and the SMTP connector and why my smart host entry on the virtual server was
ignored?
