I have a customer who bought a Dell H815dw to replace a Ricoh that went bad. I'm trying to configure the SMTP Server settings but I'm missing one thing. The old Ricoh did not use any account authentication as I believe the SMTP relay they use is setup to accept SMTP traffic from their public IP. The SMTP server is relay.appriver.com.
However there does not appear to be any way to setup this Dell H815dw for no authentication or anonymous authentication. In the "E-Mail Send Authentication" dropdown menu there is no entry for None or Anonymous. This is what I believe is stopping this Dell from connecting to the relay server.
Can anyone tell me how to configured this Dell for either anonymous or no SMTP authentication?
