Troubles with Dovecot 2.3.3 - mkdir permission denied due to +w perm: /var, dir owned by 0:0 mode=0755)

* Kunal A. via dovecot:

> Error: mkdir(/var/vmail/email1 at example.com/Maildir) failed: Permission
> denied (euid=5000(vmail) egid=5000(vmail) missing +w perm: /var, dir owned

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.
