MAILQ(1) General Commands Manual MAILQ(1) NAME
mailq - print the mail queue SYNOPSIS
mailq [-Ac] [-q...] [-v] DESCRIPTION
Mailq prints a summary of the mail messages queued for future delivery. The first line printed for each message shows the internal identifier used on this host for the message with a possible status character, the size of the message in bytes, the date and time the message was accepted into the queue, and the envelope sender of the message. The second line shows the error message that caused this message to be retained in the queue; it will not be present if the message is being processed for the first time. The status characters are either * to indicate the job is being processed; X to indicate that the load is too high to process the job; and - to indicate that the job is too young to process. The following lines show message recipients, one per line. Mailq is identical to ``sendmail -bp''. The relevant options are as follows: -Ac Show the mail submission queue specified in /etc/mail/submit.cf instead of the MTA queue specified in /etc/mail/sendmail.cf. -qL Show the "lost" items in the mail queue instead of the normal queue items. -qQ Show the quarantined items in the mail queue instead of the normal queue items. -q[!]I substr Limit processed jobs to those containing substr as a substring of the queue id or not when ! is specified. -q[!]Q substr Limit processed jobs to quarantined jobs containing substr as a substring of the quarantine reason or not when ! is specified. -q[!]R substr Limit processed jobs to those containing substr as a substring of one of the recipients or not when ! is specified. -q[!]S substr Limit processed jobs to those containing substr as a substring of the sender or not when ! is specified. -v Print verbose information. This adds the priority of the message and a single character indicator (``+'' or blank) indicating whether a warning message has been sent on the first line of the message. Additionally, extra lines may be intermixed with the recipients indicating the ``controlling user'' information; this shows who will own any programs that are executed on behalf of this message and the name of the alias this command expanded from, if any. Moreover, status messages for each recipient are printed if available. Several sendmail.cf options influence the behavior of the mailq utility: The number of items printed per queue group is restricted by MaxQueueRunSize if that value is set. The status character * is not printed for some values of QueueSortOrder, e.g., filename, random, modification, and none, unless a -q option is used to limit the processed jobs. The mailq utility exits 0 on success, and >0 if an error occurs. SEE ALSO

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. SEE ALSO
