MAILQ(8) BSD System Manager's Manual MAILQ(8)
mailq - print the mail queue
mailq [-Ac] [-q...] [-v]
mailq prints a summary of the mail messages queued for future delivery.
It may only be run by the superuser.
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 fol-
lowing lines show message recipients, one per line.
mailq is identical to "sendmail -bp".
The 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 nor-
mal 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 re-
cipients 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.

The mailq command appeared in 4.0BSD.
