I am new to sendmail. On my Sun Solaris 2.8 server, I am trying to send notification emails from an application (NetBackup) to our groupwise email system. Although I feel I have all the names correct, I continue to get DSN: User Unknown. Any thoughts?
Is an "MX" record set up for the machine that is running sendmail? Is the error message saying you are unknown or the recipient? It would be a great help to know where this message is coming from. Is this e-mail going out on the internet or LAN?
