10

The first line of this file gives the number of seconds between successive
runs of cleanq. Each time cleanq is invoked (with "svc -o /service/qscanq"),
the script will sleep for this many seconds before invoking cleanq. Any
further requests to run cleanq are ignored by the supervise process while
the script is running, so this does not result in redundant invocations.

The idea here is that running cleanq once per email message is somewhat
pointless: on a busy server, pausing before running through the queue to
delete old files allows cleanup to be batched naturally. On an unloaded
server, the length of this pause is irrelevant, and can safely be set to 1
(but might as well be left at 10).

In addition, a cron job will invoke "svc -o /service/qscanq" once
per hour, so setting this to a value larger than 3600 is perverse and
pointless.
