Courier IMAPS Server - Maildir

From Wiki

1. Install Courier (done using this page: http://www.unixreview.com/documents/s=9811/ur0506m/)

apt-get install courier-imap-ssl
This will pull down all relevant packages
Chose defaults when installing

2. Main Config is naturly enough in /etc/courier

Nothing is chanced in Courier Configs

3. To get postfix handing off to Courier:

Config Postfix (done using this page: http://www.samba.netfirms.com/courier/courier.html)
/etc/postfix/main.cnf
Comment out #mailbox_command = /user/bin/ procaine's-Y -a $DOMAIN 
Include or uncomment home_mailbox = Maildir/

4. Step 3 should automatically make a Maildir in /home/user when mail is recieved

If you want to make the maildir manually, because a maildir is required for IMAP Login:

/home/user
maildirmake Maildir
This can be done for defauly users in the skeleton account /etc/skel/

5. IMAP login and recieving emails should work ok using thunderbird 6. Now there does seem to be a load in PROCMAIL that I'm not using.

Rules can be made as to what folder to sort incoming email.
(Some basics are at: http://www.pocock.com.au/linux-doc/mbox-maildir.html)
Actually I am mixing up procmail with maildir!!
POSTFIX -> PROCMAIL (not even sure!) -> MAILDIR -> COURIER

Update Cert

Even though I'm sure its not the best practice, I copy the newly updated apache.pem cert and use it for courier-ssl.

cp /etc/apache2/ssl/apache2.pem /etc/courier/imapd.pem
/etc/init.d/courier-imap-ssl restart
