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

...
- One of the other daemons has died. qmail-send will exit as soon as
possible.
- alert: unable to
append to bounce message...

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...

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

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.
