help with Disk Usage Warning?

[cpa]

I keep getting an email from myself that says:

The account with the username 'xxx', is running out of disk space.
Please remove some files from this account, or ask the administrator to increase your disk quota.
You have currently used 87.69% of your disk space.

I have gone into each user and deleted all emails and yet it still shows disk space being used. Any ideas would be appreciated very much. Thanks in advance.

Hi,
May be problem with conflicting uid of another user. please verify it in the /etc/passwd file.
Is there any repeating entry in the /etc/passwd file correct it.
Another reason is conflicting with another existing user
Run this command
find /home -user username
If you get more than one main folder in the home directory. check the disk quota and permission of the individual folder and correct the ownership of the particular folder.
Then check the disk quota of individual folders using this command
du -csh
May be it will help to solve your problem.
