Dear Ralph,
Ah! You are right. My eyes are not working correctly. I kept thinking I was reading /va/mail/vmail etc.
Sorry for this and thank you very much for catching it!
Cheers

The error message seems pretty clear. User 'vmail' does not have write
permissions for /var, which is owned by 'root'. I suggest you create
/var/vmail and grant the necessary permissions there.
