Download Thunderbird 2 from Mozilla
(http://www.mozilla.com/en-US/thunderbird/) or other mirros like
(http://mirror.oscc.org.my/mozilla/thunderbird/). I downloaded
thunderbird-188.8.131.52.tar.gz to the directory /tmp.
Extract the files
Open a terminal and login as root to the directory /opt
su - cd /opt
- Copy the extracted forlders to /opt cp -rf /tmp/thunderbird
- Install the older library of libstdc++.so.5 (5.1 comes with
version libstdc++.so.6) yum install compat-libstdc++-33.i386
- Test the Thunderbird as a normal user /opt/thunderbird/thunderbird
- Copy the icons to the user wide pixmap cp thunderbird/icons/mozicon*.xpm
- When Thunderbird starts, it complains about the mode for
/var/spool/mail, as it cannot write to this folder. As root
do the following chmod 01777 /var/spool/mail
Add the application launcher in the panel/menu using the mozicon icon.
Only things left is to install other plugins. My first plugins are
always the Calendar (lightning) and birthday.
Taken from http://www-personal.umich.edu/~malth/gaptuning/postfix/
however note that the "your_recipients" file in the postfix main.cf,
the "plusone_recipients" in the cron job, and the "example_recipients"
in the Perl file should probably all be the same. -- wl 200808
This method consists of a simple perl script
which uses Net::LDAP to retrieve Active Directory users'
"proxyAddresses" which are both primary and secondary SMTP addresses
(as opposed to using "mail" which would only retrieve a user's primary
SMTP address). Nothing needs to be run on the Active Directory domain
controllers; this script requires only TCP port 389 access to your
Active Directory domain controllers
The resulting output is in the format: "firstname.lastname@example.org OK" which then
must be postmap(ped).
Add the following to your Postfix 2.0+ main.cf to use the
relay_recipient_maps feature of Postfix, which will now reject unknown
relay_recipient_maps = hash:/etc/postfix/your_recipients
Note: the Exchange domains in question MUST be entered in
relay_domains, and NOT in mydestination.
Also note if you would like to prevent Postfix from rejecting with
"User unknown in relay recipient table" and would rather Postfix say
"User unknown" set show_user_unknown_table_name = no in main.cf.
I have the script cronned every hour with the following cron job:
cd /etc/postfix ; ./getadsmtp.pl && postmap plusone_recipients
Conceivably this script can be easily modified to support other LDAP
servers by changing the M$-specific "proxyAddresses" search base and
CentOS specific instructions found here;
Also see the general Horde install document.
Tested on CentOS 5.1, 5.2, 5.3.
CentOS + Virtualmin Walk-through Tutorial
With Centos 5.x and a Webmin/Virtualmin installation you'll do things
# yum install horde imp
to install both the Horde general module and the Imp email IMAP
gateway. Next, run the database generation script, usually like this:
# cd /usr/share/horde/scripts/sql/
# mysql -u root -p < create.mysql.sql
You'll need to use the MySQL root password. Then, in your database
administration screen for MySQL, set the password for the new MySQL
user "horde" to something nicely random and hard to guess; keep a
momentary record as you'll need it below.
Make a copy of the default configuration, which is set to log everyone
in as Horde Administrator without a password. You'll need this if you
box yourself in, in the configuration later.
# cd /usr/share/horde/config
cp -a conf.php conf.php.everyone-as-admin
Later on you can always blitz a broken configuration by recopying the
"everyone-as-admin" script right over the conf.php.
Redirection of domain URLs to the horde system is set in Apache's
# Horde is a web application framework written in PHP.
Alias /horde /usr/share/horde
which means that
www.mydomain.com/horde [the first argument] is
mapped to the default page [index.php] in the actual filesystem's
directory. (You may have to refresh the Apache configuration if that
Then you can direct your web browser to: http://my-domain.com/horde and
fill in the Administration screens. Choose MySQL as the database. The
user is "horde" and the password is the one you set above.
For authentication method, choose "Let a Horde application handle" and
then select Imp as that application. You could pick IMAP authentication
but then your users will have to login twice (they will see "Log in to
mail" before they can get to their email).
When you click the Generate Horde Configuration button, you'll get the
text of your new conf.php ... Unless you've set the 'apache' group to
have write permission on the conf.php file, you'll have to select the
new configuration text displayed, and paste it into the conf.php ... or
use the command:
# cd /usr/share/horde/config
# cat > conf.php
and then paste (possibly with Shift+Insert) the copied text, pressing
Ctrl+D (end-of-file) to return to a prompt.
You should then be able to logout of the Horde administration page and
log back in normally as a user.
If things aren't working, check the logs. A few places to look:
/home/username/logs/error_log (for Virtualmin setup with "username")
If you get messages about "can't include" then check permissions on the
file noted; most of the php scripts should belong to group 'apache' and
have group read permissions.
Another useful step is to add yourself as an administrator. If you
didn't do that on the initial setup screens, you can edit conf.php and
modify the appropriate line to look like:
$conf['auth']['admins'] = array('Administrator'<strong>,'myusername'</strong>);
Note that you will have to manually edit the Imp mail-server
by adding, for example, the localhost with IMAP protocol:
'server' => 'localhost'
'protocol' => 'imap/notls'
'port' => '143'
The Turba Contact Manager
You might also want to install the Turba contact manager.
You can install a version found on the Turba download page
or, to be sure you have a version matching your Horde install, just do:
# yum install turba
and then following the remainder of the "Configuration" instructions in
the Turba documentation
... note that in our configuration the package is in
... you will probably want to use the 'horde' SQL database and the SQL
username 'horde' as above, keeping all the Horde data together. Consult
/usr/share/horde/config/conf.php and look for the lines like these
for the values you set above:
$conf['sql']['username'] = 'horde';
$conf['sql']['database'] = 'horde';
And then you'll run the configuration script as:
$ mysql -u root -p horde < turba_objects.mysql.sql
and then go thru the Horde admin screens, setup the Turba parameters,
and write the configuration file which in our example will be at
If you don't see Turba (shown as main heading: Organizing) in the
Horde menus, edit the main Horde configuration file (
in our case) and update the appropriate line to be:
$conf['menu']['apps'] = array('horde', 'imp', 'turba');
If you're frustrated with Emacs' default behavior of displaying characters when wrapping long lines, try this:
This only changes the way your file is displayed -- it does not insert
or remove anything from the file's contents. At the end of a line
beyond 70 characters, if there is a reasonable word-break, then a |
will be displayed (in red, if you have colors) and then the remainder
of the line will wrap to the following line.
I'm moving my internal server to new hardware and wanting to load
CentOS 5.2 ... without downloading a half dozen CDs or a 4+GB DVD
image... half of which I probably won't need, or which will be replaced
by updates anyway.
Fortunately, the latest releases have a Net install image, which is
only about 8MB. Look for this file on the mirrors:
for the 64-bit version, or as appropriate for your architecture.
Booting that CD asks about your keyboard and such, and then asks for an
Installation Method. Pick HTTP, and you'll be asked for the website and
directory. Strangely, there's no automatic list of mirrors, so you have
to do some scouting. I suggest using the mirror from singlehop
-- enter this:
Web site name: yum.singlehop.com
CentOS directory: CentOS/5.2/os/x86_64
The first file downloaded is
images/stage2.img which is about 90MB,
and then off you go.
If you're setting up a large number of servers, you probably want to
either download the ISOs or install a local mirror.
