Can you install a trusted SSL certificate on the NAS?

Hi dja,

I followed your guide and tried to get ssl certificate from https://www.cacert.org/
However, I got following error message
---------------------------------------------------------------------------------

Please make sure the following details are correct before proceeding any further.

No additional information will be included on certificates because it can not be automatically checked by the system.

The following hostnames were rejected because the system couldn't link them to your account, if they are valid please verify the domains against your account.
Rejected: zhi.homeip.net

---------------------------------------------------------------------------------

In order to verify the domain, zhi.homeip.net, it will send out a email to root@zhi.homeip.net, but i don't have mail server in my readynas duo....So, I am wondering how did you get around this problem?

Thanks
