Overview

If you have installed SquirrelMail and want to use webmail.dv-example.com domain name to access it, you will need to configure Plesk to use SquirrelMail instead of Horde Webmail. The following instructions will guide you to change the default webmail client to SquirrelMail.

Requirements

Before you start, this article has the following dependencies:

• You must have SSH access set up for root or a sudo user.
  • Connecting via SSH to your server
  • How do I enable root access to my (dv)?
  • How do I disable SSH login for the root user?

Instructions

First, you will need to redefine both HTTP(80) and HTTPS(443) VirtualHosts of Plesk Webmail and point them to the SquirrelMail location.

Create new configuration file like squirrelmail.conf and put your new virtualhost configurations into it like below:

# Non-SSL host
  <VirtualHost \
  123.123.123.123:80 \
  123.123.123.124:80 \
  123.123.123.125:80 \
  >
  DocumentRoot /usr/share/squirrelmail
  ServerName webmail
  ServerAlias webmail.*
  Alias /horde /usr/share/squirrelmail.
  <Directory /usr/share/squirrelmail>
  php_admin_flag engine on
  php_admin_flag magic_quotes_gpc off
  php_admin_value safe_mode off
  </Directory>
  </Virtualhost>
 
 # SSL host
 <IfModule mod_ssl.c>
  <VirtualHost \
  123.123.123.123:443 \
  123.123.123.124:443 \
  123.123.123.125:443 \
  >
  DocumentRoot /usr/share/squirrelmail
  ServerName webmail
  ServerAlias webmail.*
  Alias /horde /usr/share/squirrelmail
  SSLEngine on
  SSLVerifyClient none
  SSLCertificateFile /etc/httpd/conf/httpd.pem
  <Directory /usr/share/squirrelmail>
  php_admin_flag engine on
  php_admin_flag magic_quotes_gpc off
  php_admin_value safe_mode off
  </Directory>
  </Virtualhost>
 </IfModule>

Save this file to the directory /etc/httpd/conf.d. Be sure to replace IP addresses and the path to the SquirrelMail installation with your own values.

Finally, you will need to restart Apache. You should be able to access SquirrelMail at http://webmail.dv-example.com.
