[FC6] Maildir is not created

I used the Perfect Setup for Fedora Core 6 and now I added a new user with this:

Code:

useradd -m erwin
passwd erwin
**********

Then I rebooted the system. Then I checked if /home/erwin/Maildir/ exists but it is not created!

First I searched the forums here and I noticed the command maildirmake. But when I do this:

Code:

yum install maildirmake

It can't recognise the program name.

And when I do this:

Code:

maildirmake Maildir

It can't recognise the command!

So know what???
