nullmailer-queue
nullmailer-queue(8) System Manager's Manual nullmailer-queue(8)NAME
nullmailer-queue - insert mail messages into the queue
SYNOPSIS
nullmailer-queue
DESCRIPTION
This program reads a formatted mail message from standard input and safely injects it into the outgoing mail queue.
The data sent into standard input is expected to have the following format: one line containing the envelope sender, one or more lines con-
taining the recipients, a single blank line, and then the contents of the message exactly as it is to be transmitted to the destination.
All lines are terminated with a single line-feed character. All addresses must contain a fully-qualified domain name.
RETURN VALUE
Exits 0 if it successfully queues the message. If it failed to queue the message, it exits 1 and prints an error message to stdandard out-
put.
CONTROL FILES
adminaddr
If this file is not empty, all recipients to users at either "localhost" (the literal string) or the canonical host name (from
/etc/mailname) are remapped to this address. This is provided to allow local daemons to be able to send email to "somebody@local-
host" and have it go somewhere sensible instead of being bounced by your relay host.
OTHER FILES
/var/spool/nullmailer/queue
The directory into which the completed messages are moved.
/var/spool/nullmailer/tmp
The directory in which messages are formed temporarily.
/var/spool/nullmailer/trigger
A pipe used to trigger nullmailer-send to immediately start sending the message from the queue.
SEE ALSO nullmailer-inject(1), nullmailer-send(8)LIMITATIONS
This program should enforce system-wide configurable message length limits.
