Traditionally, warnquota mails all users that are over
quota, *every* time it's called. This is not always
This little patch adds funtionality to mail a overquota
user every once in a while only, no matter how often
warnquota is called.
How long to wait before mailing a user again, can be
specified in /etc/warnquota.conf with REMAIL_TIME.
Because warnquota has to keep track of the users that
are over quota, it needs to have a directory to store
this data. This directory can be specified with
OVERQUOTA_DIR. (/var/spool/overquota by default).
This patch is build against quota-tools-3.13 .
