By default (on my system), roundcube uses port 2095, which is not ssl secured. When I change the port in my browser to 2096 it is. I found this in
/usr/local/apache/conf.d/webmail.conf
ProxyPass /webmail/ http://localhost:2095/
ProxyPassReverse /webmail/ http://localhost:2095/
Can I change this to:
ProxyPass /webmail/ https://localhost:2096/
ProxyPassReverse /webmail/ https://localhost:2096/
and not break anything?
