Note: courier-imap is an imap interface, which allows reading email while it is left on the server. Works with your standard readers, such as outlook-express and netscape/thunderbird.

Note: At the time of this (original) writing, the port for courier-imap was broken, so I have always just installed from the source.

Note: this port uses expect, install expect from the ports first for added functionality:

Install expect from ports:

cd /usr/ports/lang/expect

make install WITHOUT_X11=yes

make clean

Install from the source code:

Download the tar.gz, unzip, and cd into the source folder

As a normal user, run the following commands:

./configure \

--without-ipv6 \

--without-module-authuserdb \

--without-module-authcram \

--without-module-authvchkpw \

--without-module-authldap \

--without-module-authmysql \

--without-module-authpgsql \

--without-module-authcustom

gmake

gmake check

su to root, and run the following commands

gmake install

gmake install-configure

Define Plugable Authentication Module (PAM) for imapd in /etc/pam.conf:

Note: You dont need the pop3 lines if you dont want to run pop3 server.

Note: You should have to remark out some current imap and pop3 lines.

Check the startup script:

cp /usr/lib/courier-imap/libexec/imapd.rc /usr/local/etc/rc.d/imapd.sh

cp /usr/lib/courier-imap/libexec/imapd-ssl.rc /usr/local/etc/rc.d/imapd-ssl.sh

Check the config files:

cd /usr/lib/courier-imap/etc

move *.dist to backup folder

Configuration files and changes to make:

Note: Use the LAN IP address for your imap server, and 0 for the imap-ssl server.

Now you need to generate the ssl certificate:

cd /usr/lib/courier-imap/share

./mkimapdcert

NOTE: You may have extra authdaemond daemons running, check /usr/lib/courier-imap/libexec/authlib and 'chmod a-x' the ones you dont need.
