opendmarc-importstats is a fairly trivial shell script, typically executed by cron(8), that rotates an
OpenDMARC statistics/history data file to a unique filename and then attempts to import it to a local
database for later processing by executing opendmarc-import(8). On successful import, the unique file is
removed; on failure, the script executes ls(1) on the file and exits without removing the unique file.
The intent of this last step is to cause cron to generate a message to a responsible party so that the
failure will be investigated.
