Scan to e-mail not working on your printer?

So, I was at a client today and they had issues with their printer’s scan to e-mail functionality not working properly with Exchange 2003. It’s a pretty simple fix really: Just go to the relay configuration and allow that printer and/or print server (depending on configuration) to relay to the Exchange 2003 server. The reason is, your printer is not joined to the domain and the print server you are using may not be joined to the domain. Because of this, Exchange won’t allow that printer to scan to e-mail. Just add the ip to the allowed list of your relay configuration, and it will begin functioning right away.
