Learn Linux Series (#10) - Multilingual IMAP client Roundcube

• What is Roundcube
  
  
  
  
  
  
  Roundcube Webmail is a browser-based multilingual IMAP client with an application-like user interface. It provides full functionality you expect from an email client, including MIME support, address book, folder management, message searching and spell checking. Roundcube Webmail is written in PHP and requires the MySQL, PostgreSQL or SQLite database. With its plugin API it is easily extendable and the user interface is fully customizable using skins which are pure XHTML and CSS 2.
  
  
  The code is mainly written in PHP and is designed to run on a webserver. It includes other open-source classes/libraries from PEAR, an IMAP library derived from IlohaMail the TinyMCE rich text editor, Googiespell library for spell checking or the WASHTML.
  
  
  
• How to install Roundcube
  
  
  
  We start with the installation of the necessary packages
  

sudo aptitude -y install roundcube roundcube-mysql

Answer "Yes" if you are asked for confirmation

Choose the database you will use later. "MySQL"

Enter the root password to the MySQL database

Enter the password for the RoundCube DB database

Password verification

• How to configure Roundcube
  
  
  
  first we have to edit the configuration file. To do this, enter the terminal:

sudo nano /etc/roundcube/main.inc.php

and we edit according to the scheme:

# line 72: Specifying the server IMAP (SSL):
 $rcmail_config['default_host'] = 'ssl://mail.utopian.io';

# line 75: Specifying the server port IMAP (SSL):
 $rcmail_config['default_port'] =993;

# line 135: Specifying the SMTP server (SSL):
 $rcmail_config['smtp_server'] = 'ssl://mail.utopian.io';

# line 138: Specifying the SMTP server port (SSL):
 $rcmail_config['smtp_port'] =465;

# line 142: Use of the same user name for SMTP and IMAP authentication:
 $rcmail_config['smtp_user'] = '%u';

# line 146: Using the same password for SMTP and IMAP authentication:
 $rcmail_config['smtp_pass'] = '%p';

# line 162: Determining the HELP SMTP host:
 $rcmail_config['smtp_helo_host'] = 'mail.utopian.io';

# line 271: Specifying the domain name:
 $rcmail_config['mail_domain'] = 'utopian.io';

# line 289: changing UserAgent:
 $rcmail_config['useragent'] = 'Server World Webmail';

# line 292: changing title:
 $rcmail_config['product_name'] = 'Server World Webmail';

# line 380: changing language:
 $rcmail_config['language'] = 'en_EN';

# line 649: Change of coding:
 $rcmail_config['default_charset'] = 'UTF-8';

Then edit apache.conf.

sudo nano /etc/roundcube/apache.conf

# line 4: delete '#' with:
  Alias /roundcube /var/lib/roundcube

We restart the Apache2 server.

sudo /etc/init.d/apache2 restart

Access to the page:

http://(server name or IP)/roundcube/

Disabling Suhosin encryption session.

We edit the suhosin.ini configuration file.

sudo nano /etc/php5/apache2/conf.d/suhosin.ini

Find the line "suhosin.session.encrypt = off"

and remove the semicolon "; "Before this entry.
We make sure that the equality sign is "off" (in some cases "0").

• Enable Roundcube’s Apache Virtual Host
  
  
  
  Enable the webmail.example.com virtual host you just wrote in the Creating an Apache Virtual Host with SSL section:

sudo a2ensite webmail.example.com.conf

Restart Apache to apply all configuration changes and enable your new virtual host:

sudo service apache2 restart

The output should be *

Restarting web server apache2 ... [ OK ]

If an error is given, use the error messages to troubleshoot your configuration. Missing files, incorrect permissions and typos are common causes for Apache not properly restarting.

• Setting the footer for people of a new message
  
  
  
  
  Adding a footer (signature) to each message sent via the Roundcube webmail requires changing several settings. After logging in to your e-mail account, go to the settings.
  
  
  Then select in succession: Settings tab -> Preferences -> Section tab -> Create new message
  The value of the field Create HTML messages should be changed to Always, and finally confirm the changes by clicking the Save button
  
  The footer can be defined from the option named Identity, in order for this functionality to work correctly, in the Name field, enter, for example, first and last name (each e-mail will be sent with this name). In the Signature field, enter the footer content, and finally click Save
  
  In principle, the activities described above are enough to enjoy a functional foot in the form of plain text. If you want to add, eg a logo, this is of course the most possible way. To do this, we also mark the Signature option in HTML, thanks to which we will gain access to the extended editor.

The footer will be visible in every new e-mail and in the responses to the e-mails.
