qmail-queue

qmail-queue(8)						      System Manager's Manual						    qmail-queue(8)

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).

       Programs included with qmail which invoke qmail-queue will invoke the contents of $QMAILQUEUE instead, if that environment variable is set.

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.

       All qmail-queue error codes between 11 and 40 indicate permanent errors:

       11   Address too long.

       31   Mail server permanently refuses to send the message to any recipients.  (Not used by qmail-queue, but can be used by programs offering
	    the same interface.)

       All other qmail-queue error codes indicate temporary errors:

       51   Out of memory.

       52   Timeout.

       53   Write error; e.g., disk full.

       54   Unable to read the message or envelope.

       55   Unable to read a configuration file.  (Not used by qmail-queue.)

       56   Problem making a network connection from this host.  (Not used by qmail-queue.)

       61   Problem with the qmail home directory.

       62   Problem with the queue directory.

       63   Problem with queue/pid.

       64   Problem with queue/mess.

       65   Problem with queue/intd.

       66   Problem with queue/todo.

       71   Mail server temporarily refuses to send the message to any recipients.  (Not used by qmail-queue.)

       72   Connection to mail server timed out.  (Not used by qmail-queue.)

       73   Connection to mail server rejected.  (Not used by qmail-queue.)

       74   Connection to mail server succeeded, but communication failed.  (Not used by qmail-queue.)

       81   Internal bug; e.g., segmentation fault.

       91   Envelope format error.
