NAME

qmail-log - the qmail activity record

DESCRIPTION

qmail-send prints a series of lines describing its activities. Each possible line is described below.

STARTING AND STOPPING

running: qmail-send is ready to deliver messages.
local deliveries will be put on hold: The local concurrency limit is 0, so qmail-send will not perform any local deliveries.
remote deliveries will be put on hold: The remote concurrency limit is 0, so qmail-send will not perform any remote deliveries.
number of deliveries left before exiting: ...: qmail-send wants to exit as soon as possible, usually because it was sent a TERM signal, but it has to wait for some deliveries to finish. It will not start any new deliveries.
exiting: qmail-send is done.

FATAL PROBLEMS

alert: cannot start: ...: qmail-send is unable to prepare itself for delivering messages; it is giving up. This normally indicates a serious configuration error, but it can be caused by a temporary lack of resources.
alert: oh no! lost ...: One of the other daemons has died. qmail-send will exit as soon as possible.

SERIOUS PROBLEMS

alert: unable to append to bounce message...: qmail-send is unable to record a permanent failure, usually because the disk is full. This is a very serious problem; qmail-send cannot proceed without recording the results. It will try again in ten seconds.
alert: out of memory...: qmail-send tried to allocate more memory and failed. It will try again in ten seconds.
alert: unable to opendir...: qmail-send is having trouble reading a file list from disk, usually because the system's file descriptor table is full, but possibly because permissions are set incorrectly. It will try again in ten seconds.
alert: unable to switch back...: qmail-send was sent SIGHUP, and it is unable to reenter the queue directory. This is a very serious problem; qmail-send cannot proceed outside the queue directory. It will try again in ten seconds.
alert: unable to reread...: qmail-send was sent SIGHUP, but it is unable to read the new controls. It will continue operating with the original controls.

MESSAGES

new msg m: qmail-send is going to preprocess a queued message. The message number, m, is its disk inode number. After a message is removed from the queue, its number can be reused immediately.
info msg m: bytes b from <s> qp q uid u: Message m contains b bytes; its envelope sender is s; it was queued by a user with user ID u. q is a long-term queue identifier, the process ID of the qmail-queue that queued the message.
bounce msg m qp q: Message m had some delivery failures. The long-term queue identifier of the bounce (or double-bounce) message is q.
triple bounce: discarding ...: Message m had some delivery failures, but it is already a double-bounce message, so it must be thrown away. Triple-bounce messages do not exist.
end msg m: qmail-send is about to remove message m from the queue.

DELIVERIES

starting delivery d: msg m to ...: qmail-send is telling qmail-lspawn or qmail-rspawn to deliver message m to one recipient. The delivery number, d, starts at 1 and increases by 1 for each new delivery.
delivery d: success: ...: Delivery d was successful.
delivery d: failure: ...: Delivery d failed permanently. The message will bounce.
delivery d: deferral: ...: Delivery d failed temporarily. This recipient will be retried later.
delivery d: report mangled, will defer: There is a serious bug in qmail-lspawn or qmail-rspawn. This recipient will be retried later.

WARNINGS

internal error: delivery report out of range: qmail-lspawn or qmail-rspawn has supplied a report on a nonexistent delivery. This is a serious bug.
qmail-clean unable to clean up ...: For some reason qmail-clean is unable to remove the indicated file. It will try again later.
trouble fsyncing ...: qmail-send was unable to write to disk the results of preprocessing a queued message. It will try again later.
trouble in select: There is an operating system bug.
trouble injecting bounce message...: qmail-send was unable to queue a bounce message, usually because the disk is full. It will try again later.
trouble marking ...: qmail-send was unable to record the result of a successful or permanently unsuccessful delivery. This means that the delivery will be tried again later.
trouble opening ...: qmail-send was unable to open the list of local or remote recipients for a message. It will try again later.
trouble reading ...: Either qmail-send is unable to read a recipient list, or it is unable to read the envelope of a queued message, or it is out of memory. Whatever it was doing, it will try again later.
trouble writing to ...: qmail-send was unable to preprocess a queued message, usually because the disk is full. It will try again later.
unable to create ...: qmail-send was unable to preprocess a queued message, usually because the disk is out of inodes. It will try again later.
unable to open ...: qmail-send is unable to read the envelope of a queued message for preprocessing. It will try again later.
unable to start qmail-queue...: qmail-send is unable to queue a bounce message, usually because the machine is almost out of memory. It will try again later.
unable to stat ...: qmail-send is unable to obtain information about a file that should exist. It will try again later.
unable to unlink ...: qmail-send is unable to remove a file. It will try again later.
unable to utime ...: qmail-send is about to exit, and it is unable to record on disk the next scheduled delivery time for a message. The message will be retried as soon as qmail-send is restarted.
unknown record type in ...: There is a serious bug in either qmail-queue or qmail-send.
