Some devices cannot send email to exchange 2007 after transition from 2003

I just moved to exchange 2007 from 2003.  I have a copier and a phone system that use to send messages through the exchange server.  This is no longer working after transitioning to exchange 2007.  I verified the devices have the correct exchange information.  I assume there may be something that needs to change on exchange 2007 to allow it to receive message from these devices?

Allow your devices to relay through exchange.

Both of the devices have windows domain accounts.  Do I just need to add them to an exchange group?  If so, what group?

You need to give the ip address of the machines/devices in exchange 2007. Read the article.

Yes, I did read the article.  The IP address range is already included on the default SMTP connector.  The only difference is anoymous users are not checked.  I dont see why it needs to be checked if the device has a domain account.  Do you see what I am getting at?
