21 Install SquirrelMail

To install the SquirrelMail webmail client, run

apt-get install squirrelmail

Then configure SquirrelMail:

squirrelmail-configure

We must tell SquirrelMail that we are using Courier-IMAP/-POP3:

You can now find SquirrelMail in the /usr/share/squirrelmail/ directory.

After you have installed ISPConfig 3, you can access SquirrelMail as follows:

The ISPConfig apps vhost on port 8081 for nginx comes with a SquirrelMail configuration, so you can use http://server1.example.com:8081/squirrelmail or http://server1.example.com:8081/webmail to access SquirrelMail.

If you want to use a /webmail or /squirrelmail alias that you can use from your web sites, this is a bit more complicated than for Apache because nginx does not have global aliases (i.e., aliases that can be defined for all vhosts). Therefore you have to define these aliases for each vhost from which you want to access SquirrelMail.

To do this, paste the following into the nginx Directives field on the Options tab of the web site in ISPConfig:

        location /squirrelmail {
               root /usr/share/;
               index index.php index.html index.htm;
               location ~ ^/squirrelmail/(.+\.php)$ {
                       try_files $uri =404;
                       root /usr/share/;
                       fastcgi_pass 127.0.0.1:9000;
                       fastcgi_index index.php;
                       fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
                       include /etc/nginx/fastcgi_params;
                       fastcgi_buffer_size 128k;
                       fastcgi_buffers 256 4k;
                       fastcgi_busy_buffers_size 256k;
                       fastcgi_temp_file_write_size 256k;
                       fastcgi_intercept_errors on;
               }
               location ~* ^/squirrelmail/(.+\.(jpg|jpeg|gif|css|png|js|ico|html|xml|txt))$ {
                       root /usr/share/;
               }
        }
        location /webmail {
               rewrite ^/* /squirrelmail last;
        }

If you use https instead of http for your vhost, you should add the line fastcgi_param HTTPS on; to your SquirrelMail configuration like this:

        location /squirrelmail {
               root /usr/share/;
               index index.php index.html index.htm;
               location ~ ^/squirrelmail/(.+\.php)$ {
                       try_files $uri =404;
                       root /usr/share/;
                       fastcgi_pass 127.0.0.1:9000;
                       fastcgi_param HTTPS on; # <-- add this line
                       fastcgi_index index.php;
                       fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
                       include /etc/nginx/fastcgi_params;
                       fastcgi_buffer_size 128k;
                       fastcgi_buffers 256 4k;
                       fastcgi_busy_buffers_size 256k;
                       fastcgi_temp_file_write_size 256k;
                       fastcgi_intercept_errors on;
               }
               location ~* ^/squirrelmail/(.+\.(jpg|jpeg|gif|css|png|js|ico|html|xml|txt))$ {
                       root /usr/share/;
               }
        }
        location /webmail {
               rewrite ^/* /squirrelmail last;
        }

If you use both http and https for your vhost, you need to add the following section to the http {} section in /etc/nginx/nginx.conf (before any include lines) which determines if the visitor uses http or https and sets the $fastcgi_https variable (which we will use in our SquirrelMail configuration) accordingly:

vi /etc/nginx/nginx.conf

[...]
http {
[...]
        ## Detect when HTTPS is used
        map $scheme $fastcgi_https {
          default off;
          https on;
        }
[...]
}
[...]

Don't forget to reload nginx afterwards:

/etc/init.d/nginx reload

Then go to the nginx Directives field again, and instead of fastcgi_param HTTPS on; you add the line fastcgi_param HTTPS $fastcgi_https; so that you can use SquirrelMail for both http and https requests:

        location /squirrelmail {
               root /usr/share/;
               index index.php index.html index.htm;
               location ~ ^/squirrelmail/(.+\.php)$ {
                       try_files $uri =404;
                       root /usr/share/;
                       fastcgi_pass 127.0.0.1:9000;
                       fastcgi_param HTTPS $fastcgi_https; # <-- add this line
                       fastcgi_index index.php;
                       fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
                       include /etc/nginx/fastcgi_params;
                       fastcgi_buffer_size 128k;
                       fastcgi_buffers 256 4k;
                       fastcgi_busy_buffers_size 256k;
                       fastcgi_temp_file_write_size 256k;
                       fastcgi_intercept_errors on;
               }
               location ~* ^/squirrelmail/(.+\.(jpg|jpeg|gif|css|png|js|ico|html|xml|txt))$ {
                       root /usr/share/;
               }
        }
        location /webmail {
               rewrite ^/* /squirrelmail last;
        }
