Okay, I made the change to using mailbox_transport instead of 
mailbox_command in Postfix.  I followed the above steps only having to 
change one thing.  Line 5.1 was wrong.  I needed it to say "-d ${user}" 
instead of recipient.  It was looking for user at domain instead of just 
user which is was exists in my userdb file.  I decided against putting 
everything in "/home/vmail/domain/user" because when I would log in via 
IMAP it didn't know my domain name.  I am assuming that is once again 
because my userdb only has user names and not domains.  Just I just went 
with "/home/vmail/user" and it is working.  I don't think I will be 
using more than one domain, so it should be fine.

Thanks for everybody's help with this.  Rather painless.  The only 
problem I had was with the user name but I got it resolved.
