CentOS7:
# search for roundcube config file find / -name *roundcubemail.conf* /usr/local/vesta/install/rhel/6/roundcube/roundcubemail.conf /usr/local/vesta/install/rhel/7/roundcube/roundcubemail.conf /usr/local/vesta/install/rhel/5/roundcube/roundcubemail.conf /etc/httpd/conf.d/roundcubemail.conf
# search for installed packages yum list installed |grep roundcube roundcubemail.noarch # is enough to disable roundcube rm -rf /etc/httpd/conf.d/roundcubemail.conf# seems to be no problem as well to completely uninstall it # vestacp works just as well without it yum remove roundcubemail.noarch
Debian:
VestaCP does not provide an own roundcube version, if you want to disable roundcube, you can to this for example by removing the /webmail alias from the system:
rm /etc/apache2/conf.d/roundcube.conf
service apache2 restart
if you want to re-enable it, you can create again the symlink:
ln -s /etc/roundcube/apache.conf /etc/apache2/conf.d/roundcube.conf
service apache2 restart
This will work for Ubuntu and Debian, should be a similar way for CentOS/Redhat systems. (src)
