Mail server support by James Bourne <jbourne@hardrock.org>

If you are running warnquota on a mail server you need to be able to tell
warnquota not to send mail when the users quota is either over the hard
limit or past the grace period.  So, to do this add the value:
MAILDEV = any
into /etc/warnquota.conf and warnquota will not send mail to those users.

If you have only a single partition you wish to apply this rule to, use the
device name as the argument to the MAILSERV configuration variable list
this:
MAILDEV = /dev/sdb1
Please note that specifying checking of mail device may slow down things
considerably...
