11.8 Cause Queues to Be Processed | 429
should be large to ensure that mail to busy sites, and to large mailing lists, does
not time out improperly. In observing queue processing, you might find that all
messages but one process swiftly. That one, you might find, takes more than an
hour because of a long SMTP timeout. A possible solution to this problem is to
make all timeouts short so that most queue runs are processed quickly. Then, for
example, the following command could be run a few times each night to specifically
flush those long jobs:
/usr/sbin/sendmail -OTimeout=2h -q
??? A queue can take a long time to process because too many messages are being
queued unnecessarily. Several options affect the placement of mail messages into
the queue. The QueueLA option (?§24.9.91 on page 1072) tells sendmail to queue,
rather than deliver, a message if the machine load is too high. Fewer messages
will be queued if the value of that option is increased. (Beginning with V8.14,
this load average cutoff can be more finely tuned by using the DaemonPortOptions
option??™s queueLA key; ?§24.9.27.10 on page 997.) The SuperSafe option
(?§24.9.117 on page 1096) tells sendmail to queue all messages for safety. If your
machine ???never??? crashes, this might not be necessary.
