NAME
qmail-queue - queue a mail message for delivery
SYNOPSIS
qmail-queue
DESCRIPTION
qmail-queue
reads a mail message from descriptor 0.
It then reads envelope information from descriptor 1.
It places the message into the outgoing queue
for future delivery by
qmail-send.
The envelope information is
an envelope sender address
followed by a list of envelope recipient addresses.
The sender address is preceded by the letter F
and terminated by a 0 byte.
Each recipient address is preceded by the letter T
and terminated by a 0 byte.
The list of recipient addresses is terminated by an extra 0 byte.
If
qmail-queue
sees end-of-file before the extra 0 byte,
it aborts without placing the message into the queue.
Every envelope recipient address
should contain a username,
an @ sign,
and a fully qualified domain name.
qmail-queue
always adds a
Received
line to the top of the message.
Other than this,
qmail-queue
does not inspect the message
and does not enforce any restrictions on its contents.
However, the recipients probably expect to see a proper header,
as described in
qmail-header(5).
FILESYSTEM RESTRICTIONS
qmail-queue
imposes two constraints on the queue structure:
each
mess
subdirectory must be in the same filesystem as the
pid
directory; and each
todo
subdirectory must be in the same filesystem as the
intd
directory.
EXIT CODES
qmail-queue
does not print diagnostics.
It exits
0 if
it has successfully queued the message.
It exits between 1 and 99 if
it has failed to queue the message.

indicate permanent errors:
