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. missing crypt library in main Makefile
  3. incorrect or incompatible (text-)format of install library files (*.la). Unix like library name (as provided by 'dlname') are not used under cygwin. Hence skip the related operation in the installation.

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-custom --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. The LDFLAGS and LIBS variables are used to correct the second issue. 

$ make LDFLAGS=-lcrypt LIBS=-lcrypt

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

Set ADDRESS to a valid value (0 or 127.0.0.1) and change IMAP_ULIMITD in $prefix/etc/imapd (where $prefix=/usr/lib/courier-imap) to a value accepted by the command ulimit. I simply used the existing value returned by 

$ ulimit -v

Setup authdaemon. 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)

Maildir

maildirmake is part of the courier-imap package 

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