We have a Mac Mini connected to our network and are using it as our mail server which works fine. The issue is that we have a photocopier/scanner connected to the network and we can't send scan a document to email to anyone. We have the same type of photocopier/scanner connected to another network which is linked to the main one and that doesn't have a problem. We are able to ping the photocopier from other servers and computers on the network, but not our Mac Mini, it just keeps coming up as Request timeout. It does very occasionally return 5 packets and then get the timeout request. As I said some other mac mini's we have on the network don't have a problem. We have been lead to believe that it is probably a network switch issue, but why would everything else communicate to it ok. We have tried a number of solutions to no avail. We're running on OS X 10.7.4 Please help.
You probably have to setup a connector of some sort. If this was exchange I would setup a connector to the scanner that allows emails to be sent from it.
Another option is to setup authentication without scanner to send emails
