webmail redirect doen't work!

Hi,
i’ve two virtual host:

  1. www.mydomain.it
  2. 92.13.xx.xx

In the second i’ve installed phpmyadmin and roundcube.

In the “URL for webmail redirect” of Apache settings there is: http://92.13.xx.xx/webmail
but if i try to access to webmail.mydomain.it it gives HTTP 404.

http://92.13.xx.xx/webmail works fine.

Ping to webmail.mydomain.it gives 92.13.xx.xx.

Any Ideas?

Hi,
httpd.conf doen’t change!
I manually put:

RewriteRule ^(.*) http://93.13.xx.xx/webmail/ [R]

in the VirtualHost in the httpd.conf.

Why?

I also run this:
virtualmin modify-web --all-domains --no-webmail
virtualmin modify-web --all-domains --webmail
