This is something I threw together quickly. There may be a way of
streamlining what is done here, but this does work. :-)
First, login as root and create a file in /etc called toomuchmail.txt. This
will contain the text of the warning message that you want to send.
[root@rhpsfan2 mail]# cat /etc/toomuchmail.txt
To: (address)
Subject: Mail file is too big
This is a quick note to let you know that your mail file is too large.
Please download messages that you want to keep to your own computer, and
delete them from your mail file here on the system. Thank you.
System Administrator
[root@rhpsfan2 mail]#
(The root@rhpsfan stuff is part of my system prompt. :)
Season the text of the warning message to suit your tastes. But leave that
To: line as it reads above! :-) Make it mode 644 or 600, depending on
whether or not you want your regular users to be able to read the contents
without it being mailed to them. <grin>
Next, create /sbin/mailsizecheck. This one should probably be mode 700. You
can set it 744 if you want your users to see what the script is doing. No
need to set the execute bit for regular users, since you don't want them
running the thing anyway. :-)
[root@rhpsfan2 mail]# cat /sbin/mailsizecheck
#/bin/bash
# Check mail file sizes for all users.
umask 077
rm -f /tmp/address.list # make sure it's not already there
cd /var/spool/mail
# Find the big ones and build our list of addresses....
find . -type f -size +1000k -print | sed 's/\.\///' >/tmp/address.list
# Take the list and send the warning message to each one
for address in `cat /tmp/address.list` ; do
cat /etc/toomuchmail.txt | sed "s/(address)/$address/" | \
/usr/sbin/sendmail -t ;
done
rm -f /tmp/address.list # clean up after ourselves :-)
# End of script
[root@rhpsfan2 mail]#
Then, all you have to do is setup a crontab entry which runs
/sbin/mailsizecheck once a day, and you're all set.
HTH.
