Professional installation is available.
We're going to move pretty quickly while talking about the advanced installation method of Dada Mail.
The main difference between the basic and advanced methods of
installing Dada Mail is that the advanced method saves its
configuration in an outside configuration file called,
.dada_config and we're setting up multiple
directories to save different types of file in.
Saving the configuration this way makes upgrading a lot easier and allows you to keep track of your global configuration changes.
In these directions, I'll be giving examples of shell commands you may issue to complete each step. They may need to be slightly modify to work with your particular environment. Noting too tricky, though.
If these instructions are too advanced for you, there is an alternative way to install Dada Mail, called the Semi-Automatic Advanced Installation method. It doesn't work on all hosting account setups, but it works on a surprisingly large pool of them. It's a bit of an experiment, but give it a try if the below is over your head.
(If this step is going at too quick of a pace, try doing steps, #1, #2, #5 and #6 but skip steps #3 and #4 of the Basic Installation Method)
Download Dada Mail at:
http://dadamailproject.com/download
Either uncompress the distribution on your desktop and upload
the, dada directory into your cgi-bin,
or,
upload the .tar.gz distribution itself into your
cgi-bin and uncompress on your hosting account
(you'll need an ssh connection).
gunzip dada-3_x_x.tar.gz; tar -xvf dada-3_x_x.tar; cd dada
Change the permissions of the, mail.cgi file to,
755:
chmod 755 mail.cgi
Visit the, mail.cgi script in your web browser.
You should see the following screen:

Dada Mail, complaining that it has not been
configured.
Note the URL that you used to access the mail.cgi
script. We'll be using that later.
In your home directory (preferably), create a directory
called, .dada_files. In this directory, create the
following directories:
You may use the following command:
cd; mkdir .dada_files; cd .dada_files; mkdir .archives .backups \ .configs .lists .logs .templates .tmp
A ready-to-use copy of the .dada_config file is
located in the,
dada/extras/examples/example_dada_config.txt file. Copy
the file/contents from this file into the
.dada_files/.configs directory we just set up, in a file
named, .dada_config
cd; cp public_html/cgi-bin/dada/extras/examples/example_dada_config.txt .dada_files/.configs/.dada_config
In the above command, public_html/cgi-bin/dada is the
path to the dada directory, inside the cgi-bin -
change to fit your environment.
To start off, the .dada_config file needs two
variables changed and they are the first two variables on top of
the file. They are:
Set, $DIR to the
absolute path of the .dada_files directory we
just set up. If you don't know the absolute path, change into
your .dada_files directory, and issue the, pwd
command:
cd; cd .dada_files; pwd
(prints, /home/example/.dada_files, for
example)
Set the $DIR variable to this, like so:
my $DIR = '/home/example/.dada_files';
Set $PROGRAM_URL to the URL
we used to access the, mail.cgi script in the
web browser.
We are done setting up and configuring the
.dada_config file.
The only thing the Config.pm file needs to know,
is the directory the .dada_config file lives in. If
you set the $DIR variable
inside the .dada_config file to,
/home/example/.dada_files
the directory it lives in will be:
/home/example/.dada_files/.configs
Open up the Config.pm file that's located in the
dada/DADA directory and set the variable named,
$PROGRAM_CONFIG_FILE_DIR to the directory the
outside config file lives in, like so:
$PROGRAM_CONFIG_FILE_DIR = '/home/example/.dada_files/.configs';
Save your changes.
Visit the, mail.cgi script in your web browser
again. If everything worked correctly, you should see the
following screen:

If you installed and configured Dada Mail correctly, you
should see the screen above. Good Job!
