I found & fixed the problem! It wasnt a problem with ISPConfig kextra...The fix was easy hahaha, you're gonna laugh when you hear what it was kextra1. After all of the checking on the quotas on the shell, finally....I logged into your ispconfig admin panel and checked it out.
It seems your user customer set a 10MB quota limit for their webadmin user/email account hehehehe
I set him back to -1 for you
...you might consider adding a quota note on the signup email that is sent to new customers.
That was funny
I would like to know how to get quota emails to be sent to the ispconfig webadmin instead of the server admin's email.
Can anyone shed some light on that?
Hehehe, anyways... PROBLEM SOLVED!
Talk to u later lil' cousin
