[CentOS] Experience with postfixadmin with mysql?

My first time with this.  I got postfix, mysql, and postfixadmin setup, 
generally following

http://www.campworld.net/thewiki/pmwiki.php/LinuxServersCentOS/Cent6VirtMailServer

I used postfixadmin to create my domain then added my first user and got 
an error:

Send Welcome mail: yes

Unable to send email!
The mailbox has been added to the mailbox table, but none (or only some) 
of the predefined sub-folders could be created (faxit at test.htt-consult.com)


There is nothing under /home/vmail (in postfix/main.cf: 
virtual_mailbox_base = /home/vmail)

Advise on where to start troubleshooting?  Perhaps a password or 
permissions not right?
