Created email account but no folder was created under /var/vmail

I'm facing problem that when I create a new email account, no folder was created under /var/vmail/
And I could not send or receive , even though login to round cube.

I tried chown -R vmail:mail /var/vmail   but no luck
I guess something wrong with the folder permission, user permission or cwp script did not make the folder itself
Lastly I tried to rebuild mail server from CWP , but still facing same problem
Please help

Do you still have this problem or was it already resolved?

I created folder manually inside /var/vmail and change owner to user vmail and group to vmail and everything worked for that account. I am still looking how to fix /var/vmail permission without causing other problems.

for /var/vmail user is vmail and group is mail

I can confirm that just changing /var/vmail with user vmail and group mail solved the issue.
