Help configuring email server...

[linux at bizniche.com]

Hey everyone:

For some reason, understanding how to run a for-fun email server is
beyond me.  So, I'm trying to get this configured one step at a time. 
I find some tutorials online that say..."Yeah, just setup exim,
fetchmail, squirrelmail, courier-imap, and spamassassin and you're
almost there!"  That sounds like a lot to me.  So...I'm starting small.
 First things first, I want to get exim working with courier-imap.  

Here is my setup, then I will show the errors I'm getting:

Debain Testing
exim
courier-imap
Timewarner cable
mdg.homelinux.org pointing from dyndns.org to my server.  

Here is a snip of my exim conf. (the parts that seem relevant)
=====
host_accept_relay = 127.0.0.1 : ::::1
host_auth_accept_relay = *
local_delivery:
  driver = appendfile
  group = mail
  mode = 0660
  mode_fail_narrower = false
  envelope_to_add = true
  return_path_add = true
  #file = /var/mail/${local_part}
  directory=${home}/Maildir
  maildir_format = true
  prefix=""
===================

My /etc/login.defs file has:
QMAIL_DIR    Maildir/
#MAIL_DIR             
MAIL_FILE    Maildir/

==================

And my /etc/pam.d file has:
session optional pam_mail.so standard noenv dir=~/Maildir

===================

In my home dir, I have a .forward with:
~/Maildir

I also have a folder called Maildir with mdg:mail ownership.

====================

Now, when I log into mutt, and send a test mail somewhere, it works just
fine.  Comes from mdg at mdg.homelinux.org.  When I try to mail back, I
get this header:
 ----- Message header follows -----

And I see this in my exim log:


2004-10-05 13:08:02 Start queue run: pid=5976

2004-10-05 13:08:02 End queue run: pid=5976

========================

My mail never gets delivered to ~/Maildir.  Can anyone see what I'm
doing wrong?  

Sorry for the huge email...just trying to give as much info as possible.
