Courier Imap and Quotas?

[Robert Meyer]

Why not just whip up a script to check the sizes of the users' directories and
send them hate mail when it gets above a certain size?  Judicious use of 'du
-sk' can give you all sorts of information and you can write something that
checks to see if the output of the 'du' commands yields something over your
limit and send an Email to the user (and a summary to the admin) each night. 
If it's just single mbox type files, you can use the output of 'du', 'ls -s',
'find', just to name a few.  Actually, 'find' might do it like this:
----- start of /usr/sbin/mailquotacheck -----
#/bin/sh
#
# script to find all of the Email files bigger than 5 meg and mail the user
# and the admin
#

# start a file with people over quota to send to admin
touch /var/tmp/quota$$

# go to the place to start the festivities
cd /var/spool/mail

# locate every file here over 5 meg in size
find . -size +5120k -exec '/usr/sbin/quotamail' /var/tmp/quota$$ '{}' ';'

/bin/mail -s "mail quota statistics" root < /var/tmp/quota$$
/bin/rm -f /var/tmp/quota$$
----- end of /usr/sbin/mailquotacheck -----

----- start of /usr/sbin/quotamail -----
#!/bin/sh
echo "You are currently over quota on your Email account"
echo "We have a limit of 5120 kilobytes per account"
echo -n "You are currently using: "
mailsize=`/bin/ls -s /var/spool/mail/$2 | awk '{print $1};'`
echo $mailsize kilobytes of disk space
echo
echo Please clean up your Email space
echo
echo Thank you
echo
echo The Administrative Core
echo $2 $mailsize >> $1

-----end of /usr/sbin/quotamail -----
