Are you able to see the domain in the root_cwp DB under the domains table?
No, it only shows added doimains
The user domains are shown on "users" DB.
I had created a "dummy.com" user account, and added a dummy2.com added domain, none of the 3 domains can create a mailbox from CWP USER Website.
Also, are the e-mail accounts present in the postfix DB, under the domain and/or mailbox table?
on domain show only the domain that I had created the 71 accounts.
on mailbox shows all accounts I had created.
