Each request specifies a queue file, a sender +/* address, a domain or host name that is treated as the reason for +/* non-delivery, and recipient information. +/* This program expects to be run from the \fBmaster\fR(8) process +/* manager. +/* +/* The error mailer client forces all recipients to bounce, using the +/* domain or host information as the reason for non-delivery, updates +/* the queue file and marks recipients as finished, or it informs the +/* queue manager that delivery should be tried again at a later time. +/* +/* Delivery problem reports are sent to the \fBbounce\fR(8) or +/* \fBdefer\fR(8) daemon as appropriate. +/* SECURITY +/* .ad +/* .fi +/* The error mailer is not security-sensitive. It does not talk +/* to the network, and can be run chrooted at fixed low privilege. +/* STANDARDS +/* None. +/* DIAGNOSTICS +/* Problems and transactions are logged to \fBsyslogd\fR(8). +/* +/* Depending on the setting of the \fBnotify_classes\fR parameter, +/* the postmaster is notified of bounces and of other trouble. +/* BUGS +/* CONFIGURATION PARAMETERS +/* .ad +/* .fi +/* The following \fBmain.cf\fR parameters are especially relevant to +/* this program.
