Sogo Groupware with Thunderbird

SOGo is a groupware application that has the unique capability of being able to share calendars and contacts between users via the webmail interface or the Thunderbird client. To date this is the only application that I have found that comes close to providing the most commonly used features of MS Outlook and Exchange for no software cost. It can also push Thunderbird plug-ins and settings to the Thunderbird clients.

These are the steps I used (most of this is cut and paste into a putty shell) to install this software. If you have any comments or improvements please let me know.

More details can be found here:


Minimum required ClearOS packages

  • Graphical Console
  • Mail
  • PHP
  • Web
  • MySQL

External packages

  • Thunderbird email client (optional)
  • Thunderbird SOGo plugin (optional)


Install the server software

  • Install ClearOS and configure the email, php, web and MySQL server settings and autostart.
  • Create the “sogo” service user (no password required) and make a temporary working directory:
groupadd -r sogo
useradd -mr -g sogo sogo
mkdir rpm
cd rpm
  • Download and copy files from openldap-2.2.43:
wget ""
rpm2cpio openldap-2.3.43-12.el5_5.3.i386.rpm | cpio -idmv
cp -r ./usr/lib/* /usr/lib/
rm -rf ./usr
rm -rf ./etc
  • Setup the SOGo repository:
nano /etc/yum.repos.d/SOGo.repo
  • Add and save (with these settings SOGo will get updated and only memcached will be seen from the EPEL repo):
name=Inverse SOGo Repository

name=EPEL Repository
  • Install SOGo with the MySQL backend:
yum install sogo sope49-gdl1-mysql
  • Modify the SOGo http config file <add your data here>:
nano /etc/httpd/conf.d/SOGo.conf
RequestHeader set "x-webobjects-server-port" "443"
RequestHeader set "x-webobjects-server-name" "<your server external name or IP>"
RequestHeader set "x-webobjects-server-url" "https://<your server external name or IP>"
  • Install the SOGo user and tables in MySQL <add your data here>:
mysql --user=root --password=<mysqlpassword> mysql
CREATE USER 'sogo'@'localhost' IDENTIFIED BY '<mysqlpassword>';
  • Configure SOGo <add your data here>:
service sogod stop
su sogo
defaults write sogod SOGoTimeZone "America/Phoenix"
defaults write sogod SOGoMailDomain "<youremaildomain>"

defaults write sogod SOGoMailSignaturePlacement above
defaults write sogod SOGoMailComposeMessageType html

  • Configure and start services:
service memcached start
chkconfig memcached on
service sogod restart
chkconfig sogod on
service httpd restart
  • Now you can log into the webmail interface:
https://<yourservername or IP>/SOGo

Syncing with Thunderbird

Server Side

  • Setup the Thunderbird update server to install the SOGo Connector, Integrator and Calendar:
    • Download and modify the extensions (this example is for SOGo Connector 3.104, Integrator 3.104 and Calendar 1.0b2.104i). Adjust the version numbers as required:
mkdir -p /var/www/html/SOGo-configs/WINNT_x86-msvc/temp
cd /var/www/html/SOGo-configs/WINNT_x86-msvc

mv lightning-1.0b2.104i_win32.xpi lightning.xpi
mv sogo-connector-3.104.xpi connector.xpi

cd temp
mv sogo-integrator-3.104-sogo-demo.xpi integrator.xpi
unzip -oq integrator.xpi
rm -f integrator.xpi
nano -w ./chrome/content/extensions.rdf
  • Replace “” with your servers external FQDN or IP:
    em:name="SOGo Integrator"/>
    em:name="SOGo Connector"/>
  • with:
isi:updateURL="http://<your server external FQDN or IP>/SOGo-configs/updates.php?plugin=%ITEM_ID%&amp;version=%ITEM_VERSION%&amp;platform=%PLATFORM%">
    em:name="SOGo Integrator"/>
    em:name="SOGo Connector"/>
  • Rezip the file:
zip -qr integrator *
mv /var/www/html/SOGo-configs/WINNT_x86-msvc/integrator.xpi

cd /var/www/html/SOGo-configs
rm -rf /var/www/html/SOGo-configs/WINNT_x86-msvc/temp
  • Now create the server side update script (this example is for SOGo Connector 3.104, Integrator 3.104 and Calendar 1.0b2.104i). Adjust the version numbers as required. Also replace text <your server external FQDN or IP> with your values:
nano -w updates.php

} else {
  header("Content-type: text/plain; charset=utf-8", true, 404);
  echo( 'Plugin not found' );

Client Side

  • On the client host (Windows in this case) install Thunderbird 3.X, create an account and configure it to use your COS IMAP account.
  • Download and install the modified integrator.xpi add-on.
  • The next time you start Thunderbird and login the Integrator will download and install the Connector and Calendar automatically.
  • You can also use the “extensions.rdf” and “updates.php” scripts to install other add-ons and make configuration settings in the Thunderbird client.

Please let me know if you find any errors or omissions. If you have a better way of doing this please let me know too. I am always looking to do things better (my wife has quite an extensive list of suggestions)! I believe the “updates.php” could be automatically created with a script based on the “xpi” files in the folder. search?q=clearos%2C%20clearos%20content%2C%20kb%2C%20howtos%2C%20clearos6%2C%20skunkworks%2C%20categoryserver%2C%20maintainer_dloper&amp;btnI=lucky
