Found a resource at http://support.lunarpages.com/knowledge_bases/article/20 for my webmail problem.
1. Create subdomain: webmail.domain.com
2. add .htaccess file below to forward to to horde email. Even non-https. Yeah!!
To Redirect to the Horde Webmail Client:
RewriteEngine on
RewriteCond %{HTTP_HOST} ^webmail.yourdomain.com$ [OR]
RewriteCond %{HTTP_HOST} ^www.webmail.yourdomain.com$
RewriteRule ^(.*)$ http://yourdomain.com:2095/horde/$1 [R=301,L]
To Redirect to the Squirrel Mail Client:
RewriteEngine on
RewriteCond %{HTTP_HOST} ^webmail.yourdomain.com$ [OR]
RewriteCond %{HTTP_HOST} ^www.webmail.yourdomain.com$
RewriteRule ^(.*)$ http://yourdomain.com:2095/3rdparty/squirrelmail/index.php$1 [R=301,L]
Secure ya want????
You can also use a secure login to the webmail as well, for the line:
RewriteRule ^(.*)$ http://yourdomain.com:2095/horde/$1 [R=301,L]
change this to:
RewriteRule ^(.*)$ https://yourdomain.com:2096/horde/$1 [R=301,L]
same applies for Squirrel Mail:
RewriteRule ^(.*)$ http://yourdomain.com:2095/3rdparty/squirrelmail/index.php$1 [R=301,L]
change this to:
RewriteRule ^(.*)$ https://yourdomain.com:2096/3rdparty/squirrelmail/index.php$1 [R=301,L]
