How do I free up some space?  I've already deleted about 5000 email messages and rebooted the server (FreeBSD 4.0) about 4 times with the same messages.  Got any ideas and directions?Thanks,Tom

df -h

to get an idea of how full your disks are, example output:

Filesystem    Size   Used  Avail Capacity  Mounted on
/dev/ad0s1a   197M    64M   118M    35%    /
/dev/ad0s2e    14G   2.4G    11G    18%    /home
/dev/ad0s2f    14G   4.8G   8.5G    36%    /opt
/dev/ad0s1e   4.3G   1.9G   2.1G    48%    /usr
/dev/ad0s2g   2.9G  1010M   1.7G    37%    /var
procfs        4.0K   4.0K     0B   100%    /proc

Then also try:

du /var | sort -n

which will show you how much disk usage /var is taking up and sort it so that the larger
files are to the end of the listing.  If you notice anything untoward you might want to
backup or delete.

Also check that your logfiles are being compressed under /var/log and that they're rotated
and preferably backed up out of the /var hierarchy.

Just some ideas,
