Email receiving problems

[Kelly <webmaster@boredomsoftware.com>]

I am working with a test box trying to get a test environment running to 
switch from Solaris to Debian. 

I am having a problem with my email.  I am running 'Postfix' SMTP 
server.  I am running the 'Courier IMAP' server.  I can send email just 
fine.  When I am receiving email there is a problem.  The email is 
supposed to go to the 'maildirs' directory in the home folders for the 
users.  Problem is the email goes to the /var/mail/$username directory.

Anyone have an idea of what I did wrong?

Thanks

Kelly
