====== Webmail ======

We chose [[http://roundcube.net | RoundCube]] after trying a bunch of other webmail applications. Here are some that we tried:

  * Bongo (formerly Hula) - could not get it to install
  * SquirrelMail - old UI is hard to work with
  * Horde (IMP) - complicated setup, does too much
  * Zimbra - too integrated with email servers

===== Installation =====

First, install the prerequisites (and their dependencies):

<code bash>
sudo yum install -y php53-gd php53-intl php53-mbstring php53-xml
</code>

Next, create the directory to store the program in:

<code bash>
SITE=webmail.sluug.org
APACHE_USER=apache
sudo mkdir /srv/www/$SITE
sudo chown -R $APACHE_USER:$APACHE_USER /srv/www/$SITE
sudo chmod g+s /srv/www/$SITE
</code>

Get the latest version of the RoundCube code from the Subversion repository:

<code bash>
cd /srv/www/$SITE
sudo svn checkout --trust-server-cert --non-interactive https://svn.roundcube.net/trunk . ;# Accept the certificate.
sudo rm -f public
sudo ln -s roundcubemail public
sudo chmod ug+w roundcubemail/logs roundcubemail/temp
sudo chown -R $APACHE_USER:$APACHE_USER roundcubemail
</code>

Prepare the MySQL database. Be sure to save the username and password in the ''/root/.my.cnf'' file. (Use the real password and username below.)

<code bash>
PASSWORD=$PASSWORD
USER=$USER
sudo -H mysql <<EOF
CREATE DATABASE roundcube;
GRANT ALL PRIVILEGES ON roundcube.* TO $USER@localhost IDENTIFIED BY '$PASSWORD';
FLUSH PRIVILEGES;
EOF
</code>

Make sure there's an Apache configuration for the site, and reload the Apache config if necessary.

===== Configuration =====

Browse to ''http://webmail.sluug.org/installer/''.

  * Click ''START INSTALLATION'' button.
  * Make sure all the requirements are met. Try to enable as many of the optional items as well.
  * Click ''NEXT''.
  * In ''General Configuration'':
    * product_name = SLUUG Webmail
    * CHECK ip_check
    * CHECK Cache messages in local database
  * In ''Database Setup'':
    * Database name = roundcube
    * Database user = $USER from above
    * Database password = $PASSWORD from above
  * In ''IMAP Settings'':
    * default_host = ssl:/\/sluug.org
    * port = 993 (for IMAPS)
    * username_domain = sluug.org
    * CHECK auto_create_user (allows automatic use for any IMAP user on our system)
  * In ''SMTP Settings'':
    * smtp_server = localhost
    * smtp_port = 25
    * smtp_user/smtp_pass = (blank)
  * In ''Display settings & user prefs'':
    * pagesize = 12
    * UNCHECK prefer_html
    * CHECK preview_pane
    * draft_autosave = 3 min
  * Click on ''CREATE CONFIG'' button.
  * Save the 2 config files.
    * Note that the ''download'' links don't work (they give a default config, not the one you just built); you'll have to cut and paste.
    * Save the files in ''/srv/www/webmail.sluug.org/roundcubemail/config/'' with names of ''main.inc.php'' and ''db.inc.php''
  * Hit the ''CONTINUE'' button.
  * The next page will test the config to see if everything is OK.
  * The DB Schema will show as ''NOT OK (Database not initialized)''
  * Click on the ''Initialize database'' button.
  * Now the DB Schema should show as ''OK'', along with DB Write and DB Time.
  * Next, skip down to the ''Test SMTP config'' section.
  * Enter a sender and recipient, then click the ''Send test email'' button.
  * The page should come back with ''SMTP send: OK''.
  * Next, skip down to the ''Test IMAP config'' section.
  * Enter login info for an account on the IMAP server and click ''Check login''.
  * The page should come back with ''IMAP connect: OK''.

Additional configuration can be done in the ''/srv/www/webmail.sluug.org/roundecubemail/config/main.inc.php'' file.

Remove the installation directory and some other files that are not needed:
<code bash>
cd /srv/www/webmail.sluug.org/public
sudo rm -rf installer/ README INSTALL UPGRADING LICENSE CHANGELOG
</code>


===== Upgrading =====
**NOTE: It is highly recommended to ensure that nobody is logged into the webmail system when upgrading.**

First, make a backup of the current version, just in case.
<code bash>
cd /srv/www/webmail.sluug.org
sudo cp -a roundcubemail roundcubemail.backup-`date +'%Y%m%d'`
</code>

Since we're using Subversion to download the code, we can simply pull the latest revision. First, check the current revision info:
<code bash>
cd /srv/www/webmail.sluug.org
svn info
</code>

Then update to the latest revision:
<code bash>
cd /srv/www/webmail.sluug.org
sudo svn up
svn info
</code>

Check the config files, to add any new parameters:
<code bash>
cd /srv/www/webmail.sluug.org
diff -u roundcubemail/config/db.inc.php roundcubemail/config/db.inc.php.dist 
diff -u roundcubemail/config/main.inc.php roundcubemail/config/main.inc.php.dist 
</code>

Change anything necessary in the config files, then check the installation by browsing to ''/installer/''.

Once everything checks out, remove the unnecessary files again:
<code bash>
cd /srv/www/webmail.sluug.org/public
sudo rm -rf installer/ README INSTALL UPGRADING LICENSE CHANGELOG
</code>
===== Usage =====

Browse to ''http://webmail.sluug.org/''.
Log in with credentials against the IMAP(S) server.
===== TODO =====

Use PostgreSQL instead of MySQL.

Install PHP FileInfo package, which is optional, but recommended.

Consider configuring the logging differently.
