Mailempfang nicht für alle System-Accounts

Hallo Leute,

gibt es eine Möglichkeit, das mein Postfix nicht alle mails für user annimmt, die einen system-account haben?
Ich möchte also das Postfix die eingehenden mails für z.B. sys@xx oder backup@xx zurückweist.
es wäre toll, wenn ich nicht gleich eine db dafür anlegen muss.

Gruß und Danke
