Incorrect DiskSpace and Information in cPanel

While working on one clients vps for incorrect disk usageĀ  stats for mails

While the default cpanel has no emails the usage stats showed 750MB.

After going through I found a issue which was causing this

The file causing this issue was maildirsize

maildirsize is the file which shows stats information for each account

root@vps [/home/designse]# find . -iname maildirsize

I went ahead and deleted the file to fix this issue.
root@vps [/home/designse]# cd mail/
root@vps [/home/designse/mail]# rm -rf maildirsize
root@vps [/home/designse/mail]#

Now all stats shows right details
