I am using Plesk 7.5.4 on Windows 2003. If I view the Mail preferences for a domain on my server, I can choose one of 3 default actions for nonexistent user email: bounce, catch-all, or discard. I also know that in a domain template I can set one of the same 3 as the default action. My question revolves around the use of the CLI to select this "Discard" option. domain_pref.exe --help, and the online CLI documentation seem to indicate that the -no_usr argument only accepts two values: "bounce:txt" or an email address. Is the documentation just outdated or is it really not possible to "Discard" via the CLI? I don't know if this is relevant, but I am using the SmarterMail mail server.
