Anyone have any suggestions on this one?
Old HP MFPs like 4345 and other applications have no problem connecting to our Domino SMTP gateway, but the newer models like M425 and M510 are proving a problem. The SMTP is responding normally to telnet testing.
Do I need to use TLS and a certificated connection and authentication or is there a simple stupid way of simply getting this to work?
