mailq - print the mail queue
mailq [-Ac] [-q...] [-v]
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 mes-
sage. 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.
Limit processed jobs to those containing substr as a substring of the queue id or
not when ! is specified.
Limit processed jobs to quarantined jobs containing substr as a substring of the
quarantine reason or not when ! is specified.
Limit processed jobs to those containing substr as a substring of one of the recip-
ients or not when ! is specified.
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, ran-
dom, 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.
The mailq command appeared in 4.0BSD.
