Re: SMTP Relay Best Practice Question

I've not used that method of allowing relay because I've heard that it is
not reliable.

Thanks!

By identifying the device by IP under the relay tab as an allowed device,
this should allow that device to relay email thru the BE Exchange server,
correct?

I tried this with a member server and the NOD32 anti-virus application. I
configured the apps to send the notification to my gmail address, added
the
servers IP to the relay tab, and restarted the SMTP VS. The email was not
relayed until I added SMTP credentials to the app. Then it would relay
just
fine.

I assume that I am missing a step somewhere in the process?

What I usually recommend is that you configure the back-end server to
allow
relay, and ensure that your firewall does not expose this host to the
Internet. With such a configuration you can have an open relay without
risk
of it being used by a spammer.

I have several MFP devices on our network that I would like to configure
Exchange to relay mail for. I want to make sure that my understanding
is
correct before I start configuring these devices.

I have Windows 2003/Exchange 2003 SP2 install in a FE/BE configuration.
At
this time, I have not defined a routing group or a bridgehead server,
however
that will likely be next in the configuration process.

On the BE server, I should configure relay to allow "Only the list
below"
with specific IPs for the specific devices that require it. I should
also
leave the check box that allows all authenticated computers to relay.

Is my thinking correct? Or should I instead let the entire local
network
relay? I assume that could potentially become a huge risk though.

If my above thinking is correct, will the configuration of a routing
group
and a bridgehead server to send all email out thru the FE server affect
the
above configuration?

Thanks for all the help!
