maildirmake: /opt/mail/testdomain.com/user1: No such file or directory

[mangia]

Hello...

I'm working on new mail server and I'm trying to do it like it is on http://www.howtoforge.org/virtual_us..._clamav_centos

but...

maildirmake /opt/mail/testdomain.com/user1 is not ok. It returns an error maildirmake: /opt/mail/testdomain.com/user1: No such file or directory

I searched on the Internet and found that I should do
# mkdir -p /opt/mail/testdomain.com/user1

Then
# maildirmake /opt/mail/testdomain.com/user1/Maildir

# maildirmake -q 20971520S /opt/mail/testdomain.com/user1/Maildir

Is this correct or I need to find something else?
I don't know how is it possible that no one didn't notice this?

This howto has so many bugs....
