Mail being sent to /home/User/Maildir but its checking /var/spool/mail/User

The mail is being sent to the proper location, /home/User/Maildir/etc..., but I think when I try to check for new messages it is checking /var/spool/mail/User instead of where the mail is being delivered. I have been trying to figure out why, but have been struck at dead ends and finding I am doing the same thing over and over ... I am at a loss as to why it is doing this and as to where to find a solution.

I am useing CentOS 3.X useing the Fedora Core 3 Perfect Setup guide as a reference.

I do not recieve any error messages in the maillog so it must be a configuration error but I just don't know where to fix it.

 

You could also install Dovecot. It also uses Maildir.

 

I have courier installed, at least I think I do. I used the same install lines for the Fedora guide, just replaced apt-get with yum.

Code:

# yum install cyrus-sasl cyrus-sasl-devel cyrus-sasl-gssapi cyrus-sasl-md5 cyrus-sasl-plain postfix imap

Could it be that I am just over looking something ?

 

You've installed the imap package which uses mbox, not Maildir.
