Redirect /webmail to webmail.example.com

To redirect example.com/webmail to webmail.example.com, follow these steps:
On the webserver, create a config file for Apache:

Code:

nano /etc/apache2/conf-available/roundcube-redir.conf

and put this in there:

Code:

Redirect /webmail https://webmail.example.com

Then enable the config:

Code:

a2enconf roundcube-redir

and reload Apache2

Code:

systemctl reload apache2

Now, if you go to example.com/webmail, you will be redirected to webmail.example.com (with a 302 redirect).


Replace example.com with your own domain

 

I suggest changing this to

Code:

rewrite ^/webmail$ https://webmail.example.com redirect;

for the following reasons:
- Temporary redirect instead of permanent - in case your client moves to a different hosting company
- Redirect to https instead of http
- Redirect /webmail instead of /webmail/

 

To create the site "webmail.example.com":
- Create DNS record for webmail.example.com
- Create site webmail.example.com, enable Let's Encrypt, disable auto subdomain
- Under the tab "Options", add this to Apache directives:

Code:

DocumentRoot "/var/lib/roundcube/public_html"
Alias "/stats" "{DOCROOT}/stats"
