Can Exchange accept mail from unauthenticated local device?

We have an old-ish Minolta copier (Pitney Bowes DL 460 OS) that supports sending scans by e-mail, but doesn't have any mechanism for SMTP auth or any other kid of auth that I can see.  It has a setting to type nit he mail server, and I put the IP of the Exchange box there.  When I try sending, it gives a generic "SMTP error" message.  The only setting on the copier other than SMTP server address is reply-to address.  There, I've tried using my user@domain.local as well as user@domain.com addresses, with the same result.  I think what is happeneing is probably that Exchange is rejecting the mail due to a lack of authentication.

We are running Exchange 2010 on Small Business Server 2011, and I'd like to somehow set up the particular local IP of that copier/scanner as trusted so that Exchange will always accept mail from it.  Is there a way to do that?

Yes, on the SMTP properties there is a section where you can "Deny mail from all but the IP's listed below" insert your minolta's IP and that should allow it to send email. You will do this on the SMTP connector.

Meganum3 - I tried that suggestion, and the connector seems to be set up ok, but I am still getting errors from the copier.  I haven't seen a way on exchange yet to look at an SMTP log.  How can I monitor what is coming in on my new connector (port 25 on new IP)  to see what's going on?

Wish Marketing would stop bothering you?

Is your marketing department constantly asking for new email signature updates? Are they requesting a different design for every department? Do they need yet another banner added? Don’t let it get you down! There is an easy way to manage all of these requests...

You need a recieve connector under the Server Configuration->Hub Transport. Set it's Network to receive from your copiers IP address.

Then under Organization Configuration->Hub Transport->{SMTP Transport:Internet Mail} and then set it's source server to your recieve connector name that is in the server configuration.

I found this: http://technet.microsoft.com/en-us/library/bb124531.aspx to enable the SMTP log, and that got me the rest of the way there.  (secondary problem turned out to be incorrect e-mail address programmed into a button) Thanks!

New problem to note for future searchers.  Apparently adding an additional IP to the NIC for use in implementing the approved solution broken DHCP on the SBS server.  Normally, you wouln't run DHCP on your Exchange server, so this may not affect many users, but for SBS, it will.  The effect was that once adding the new IP and binding the receive connector to it, the DHCP service would refuse to start.  I'm going to post another question to try to sort this out.
