Redirect webmail.domain to Usermin

Yeah, only the one is redirected.

If you want to redirect additional addresses, you could always add it in manually.

You can add custom Apache directives using the server templates, in System Settings -> Server Templates -> Default -> Apache Website, and you can add custom directives in the textbox labeled "Directives and settings for new websites".

Obviously there is only one "magic" URL for this...so, you'd have to manually add it to the Server Templates.

So, you'd need to add a ServerAlias:

ServerAlias www.webmail.${DOM}

And then the Rewrite rules:

RewriteEngine on
RewriteCond %{HTTP_HOST} =www.webmail.${DOM}
RewriteRule ^(.*) https://${DOM}:20000/ [R]

Or, you could explicitly set the destination to your main domain instead of using ${DOM}:20000.

I'm not sure if having two RewriteEngine directives will cause breakage though...you should test it before leaving it setup this way in production. I'm not sure how it could be done if this extra directive causes a problem.

I'm also not really sure why it's useful to have www at the front. ;-)
