Creating a Webmail Sub-Server

Hi,

First, I'll try to explain what I want to do, then I'll explain what I did, then I'll ask the best way to get there from here.

Basically, I want to configure a different default webmail other than Usermin. Yes, we have done this for years, but I'd like to do it 'right'.

I've been looking at https://www.virtualmin.com/documentation/id%2Cwebmail_and_virtualmin.

I don't mean to be rude, but I have never met anyone that likes Usermin for webmail. I find that it is very frustrating for IMAP accounts with many folders. But it does have those nice buttons for spam handling...

In the past, I just installed RoundCube into a folder of our main web site, accessed as https://mydomain.com/rc. This works.

I started thinking about how I could make everything to do with 'admin' and 'webmail' redirects work without throwing SSL warnings...that was my first mistake...thinking.

So, I thought I would create a new sub-server 'webmail.mydomain.com' and install RC there which would use the proper SSL cert for no warnings. However, I got the error:

"Failed to create virtual server : The domain webmail.mydomain.com is already hosted by your Apache webserver"

So, I dug references to 'webmail.mydomain.com' out of the Apache conf file, restarted Apache, and I was then able to create the sub-server 'webmail.mydomain.com'.

After thinking some more, I thought I had better ask you if that was a good idea?

Is there a better way? (we're pretty set on using the name 'webmail.mydomain.com').

Ultimately, after it is all working well, I plan to modify the template and use CLI commands like:

virtualmin modify-web --all-domains --no-webmail

virtualmin modify-web --all-domains --webmail

Basically, I hope to redirect to the primary domain name and use the existing SSL cert with zero warnings. Come to think of it, why don't you guys already do that? ;-)

Would it be possible to do something similar with the 'admin.mydomain.com' redirects?

Is it possible to give RoundCube 'buttons' for spam handling (like Usermin)?

Is there any way to automatically configure 'from addresses' (identities) for users of RoundCube? It would be a drag to tell users to use webmail that they have to configure before use...

Thanks in advance,

G
