Each request specifies a queue file, a sender +address, the reason for non\-delivery (specified as the +next\-hop destination), and recipient information. +The reason may be prefixed with an RFC 3463\-compatible detail code; +if none is specified a default 4.0.0 or 5.0.0 code is used instead. +This program expects to be run from the \fBmaster\fR(8) process +manager. + +Depending on the service name in master.cf, \fBerror\fR +or \fBretry\fR, the server bounces or defers all recipients +in the delivery request using the "next\-hop" information +as the reason for non\-delivery. The \fBretry\fR service name is +supported as of Postfix 2.4. + +Delivery status reports are sent to the \fBbounce\fR(8), +\fBdefer\fR(8) or \fBtrace\fR(8) daemon as appropriate. +.SH "SECURITY" +.na +.nf +.ad +.fi +The \fBerror\fR(8) mailer is not security\-sensitive.
