mailstat [-klmots] [logfile]
mailstat parses a procmail-generated $LOGFILE and displays a summary about the messages delivered to all folders (total size, average size, nr of messages). The $LOGFILE is truncated to zero length, unless the -k option is used. Exit code 0 if mail arrived, 1 if no mail arrived.
Customise to your heart's content, this program is only provided as a guideline.
