Best way to redirect <client_site>/roundcube to webmail.<client_site> for all sites?

I'm migrating all clients from previous non-ISPConfig VPS. On that VPS all sites were automatically assigned redirection of Roundcube to webmail.<client_site> and to make the migration seamless for them, I would like to prepare the same on this new ISPConfig VPS.
What would be the recommended way to achieve this? Thanks.

 

I see. That could work well for me. So, where do you usually put the directive, .htaccess, /etc/apache/sites-available/<client_site>.vhost file or is it somewhere in ISPConfig?

Thanks ThOm.

 

I'll go with your usual way for now but I'm definitely interested in automating this in the future. Maybe I'll play with Jesse's idea later.
Thanks guys!

 

I'm now able to access roundcube on the Webmail subdomain. The only problem is the Document root is applied no only to the webmail domain, but also to the main site. I think ideally, there needs to be a field where "apache directives" can be entered for each subdomain?
Since there isn't, should I put it directly in /etc/apache2/sites-available/mydomain.com.vhost? Will it get over-written by ISPConfig at anytime or is it safe to do?

 

I tried using httpd <if> statements as below in the apache directives box, but as soon as it see's the DocumentRoot is refuses to copy it into the vhost file. If I replace that with something else it gets copied (but obviously doesn't help me).

Then (before I saw your warning above) I tried editing the vhost file directly, which worked a treat, except it seems at some point it will stop working (maybe at server restart)?

The changes I made were to <VirtualHost *:443>. I commented out the document root and added the new one and I commented out the original ServerAlias and left the "webmail" one.

Is there somewhere else I can make those changes? I don't think I can do this in the apache directive area in the panel because it will redirect the entire domain to roundcube and most customers will want their own content on their main domain. Any thoughts please?

 

I just saw this! Sorry!
This could work. I will give it a try. Thanks.

 

Decided to initially keep it simple. I'll just get it working individually per domain to start with and will look into more elegant solutions later. With this in mind I:

• Added new site but specified the domain as webmail.example.com. I checked Let's Encrypt and set the DocumentRoot to "/var/lib/roundcube"
• Checked the redirect to SSL option
• Added an A record into the existing example.com zone, for 'webmail'

Upon checking, the SSL certificate being used turned out to be the one my ISPConfig was using, not the one for example.com, so I went back to Sites > webmail.example.com to check and LE was unchecked! I checked it again, closed the record and returned to it again after the ongoing tasks were completed and found it unchecked again!

Not sure what might be causing this. Any ideas? Thanks.

 

Excellent. With that info, I was able to try again after propagation and it's now working. Thanks Th0m
