.TH ERROR 8 .ad .fi .SH NAME error \- Postfix error mailer .SH SYNOPSIS .na .nf \fBerror\fR [generic Postfix daemon options] .SH DESCRIPTION .ad .fi The Postfix error mailer processes message delivery requests from the queue manager. 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. .SH SECURITY .na .nf .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. .SH STANDARDS .na .nf None. .SH DIAGNOSTICS .ad .fi 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. .SH BUGS .ad .fi .SH CONFIGURATION PARAMETERS .na .nf .ad .fi The following \fBmain.cf\fR parameters are especially relevant to this program.
