Courier-IMAP

Courier-IMAP requires the installation of the Courier Authentication Library and the following cygwin tools and packages

  • patch, tar, make, gcc
  • crypt
  • libgdbm-devel
  • libtool (version 1.5.27a-1)
  • inetutils
  • cygrunsrv

Run the Cygwin setup program. Locate, select and install the required packages.

Courier Authentication Library

Download and untar courier-authlib in your favorite sandbox. Version used: 0.61.0

Apply the [{{#file:courrier-authlib-0.61.0-cygwin.patch}} patch] before configuration to correct following issues:

  1. incorrect usage of EXEEXT in makedat/Makefile
  2. add libtool flag (-no-undefined) required for DLL creation
  3. add missing dependencies
  4. add PATH in start script to access new DLL (installed in a different directory)

Install the patch 

$ patch -Np1 < courrier-authlib-0.61.0-cygwin.patch

Configure the package without most authentication modules, keeping only userdb.

Note: replace mailuser by an existing user name (in your /etc/passwd file). I used my own username. 

$ ./configure --disable-root-check --with-waitfunc=wait --without-authpam --without-authldap --without-authpwd \
--without-authshadow --without-authcustom --without-authpipe --without-authmysql --without-authpgsql --with-mailuser=mailuser \
--with-mailgroup=mkgroup-l-d

Take a long pause... and when ready execute the following command. 

$ make

Take again a long pause... then check the result and install the libraries 

$ make check
$ make install

Compilation and installation

Download and untar package courier-imap in your favorite sandbox. Version used: 4.4.1.20080920

Apply the [{{#file:courrier-imap-4.4.1-cygwin.patch}} patch] before configuration to correct following issues:

  1. incorrect usage of EXEEXT in makedat/Makefile
  2. incorrect usage of EXTEXT in main Makefile
  3. remove usage of /usr/lib/env in start/stop script (/usr/lib/env does not seem to work under Cygwin)

Install the patch 

$ patch -Np1 < courrier-imap-4.4.1-cygwin.patch

Configure the package 

$ ./configure --disable-root-check --with-waitfunc=wait

Take a walk... and when ready execute the following command to build the package. 

$ make

Time to go for some coffee... and then install the package with the usual 

$ make install
$ make install-configure

Configuration

Setup courier-imap: $prefix/etc/imapd (where $prefix=/usr/lib/courier-imap)

Set ADDRESS to a valid value (0 or 127.0.0.1) and change IMAP_ULIMITD to a value accepted by the command ulimit. I simply used the existing value returned by 

$ ulimit -v

Setup authdaemon: /usr/local/etc/authlib/authdaemonrc. Create authdaemonrc file 

$ cp /usr/local/etc/authlib/authdaemonrc.dist /usr/local/etc/authlib/authdaemonrc

Change number of daemons (I use only one) and enable DEBUG_LOGIN 

# The number of daemon processes that are started.
daemons=1

# DEBUG_LOGIN=2   - turn on debugging + log passwords too
DEBUG_LOGIN=2

IMAP accounts

User accounts and settings are managed by userdb. See makeuserdb man page for details, or used the freshly new install man page - man makeuserdb

Assuming username is your username, 1001 and 10545 are respectively the UID and GID of an existing user (part of your /etc/passwd and /etc/group). I use my own UID and GID. Create the mailuser home directory, if required. Create Maildir folder. 

$ mkdir -p /home/username
$ cd /home/username
$ /usr/lib/courier-imap/bin/maildirmake Maildir

Create the userdb text file /usr/local/etc/authlib/userdb 

$ touch /usr/local/etc/authlib/userdb
$ chmod 700 /usr/local/etc/authlib/userdb

Edit /usr/local/etc/authlib/userdb, one line per account 

username[TAB]uid=1001|gid=10111|home=/home/username|mail=/home/username/Maildir|systempw=XXXXXX

where XXXXXX is the encrypted password created with 

$  /usr/local/sbin/userdbpw.exe

Create the (binary) userdb 

$ /usr/local/sbin/makeuserdb

You should now have the following files created:

  • /usr/local/etc/authlib/userdb.dat
  • /usr/local/etc/authlib/userdbshadow.dat

Running

Install and configure syslogd. Run the Cygwin setup program. Locate, select and install inetutils (contains syslogd). Configure syslogd with the following command. It will create the /etc/syslogd.conf file and install a windows service using cygrunsrv 

$ syslogd-config

Start the authlib and imap daemons with the following command: 

$ /usr/local/sbin/authdaemon start
$ /usr/lib/courier-imap/libexec/imapd.rc start

Stop the daemons with the following command: 

$ /usr/lib/courier-imap/libexec/imapd.rc stop
$ /usr/local/sbin/authdaemon stop

You'll find log messages in /var/log/messages (default target file as specified in /etc/syslogd.conf) 


#! /bin/sh
#
# Courier imap daemon startup script.

authlib=/usr/local/sbin/authdaemond
imapd=/usr/lib/courier-imap/libexec/imapd.rc

Testing authlib

$ /usr/local/sbin/authtest username CCCCCC
Authentication succeeded.

     Authenticated: username  (uid 1001, gid 10111)
    Home Directory: /home/username
           Maildir: /home/username/Maildir
             Quota: (none)
Encrypted Password: XXXXXX
Cleartext Password: CCCCCC
           Options: (none)

where username is you user name and XXXXXX is you encrypted password as provided in userbd text file. CCCCCC is your password in clear.

Troubleshooting

Should you have a doubt on the execution of a command (ie: no output) you can check if the application is able to load required DLL. This error is not reported. Using strace, windows will complain about DLL not found, if any. To solve this problem you may need to add some path in your PATH. For example, in order to test authlib with authtest: 

$ strace /usr/local/sbin/authtest
    # This will open a dialog box to complain about DLL.
$ export PATH=$PATH:/usr/local/lib/bin
$ /usr/local/sbin/authtest ausername

Maildir

maildirmake is part of the courier-imap package 

$ /usr/lib/courier-imap/bin/maildirmake
