Alias /webmail /var/www/roundcube
to access roundcubemail. It seems I touched the wrong skrew, because now I get error 403 when I call http://www.domain.xyz/webmail
(domain is located in /var/www/domain.xyz/web)
but I do not recall what I did...
The log says:
client denied by server configuration: /var/www/roundcube/
