Please forgive my bad English.
VestaCP is a great hosting panel but there's a base feature missing - Users limitation for quota .
I know vesta doesn't have any built-in notification system for soft/hard limit on user quota.
I played with warnquota It appears that his trying to send email to user system email instead of vesta user email.
The system email is: username@hostname so root will get NDR error.
Here's a common use steps :
Step 1: Notify the user in case of disk or bandwidth is near the end.
Step 2: Block the user service after exceeded is reached.
If bandwidth is exceeded then we can change the user sites template to exceeded mode.
I did some search on the forum before and nothing came up ..
Thanks in advance
