Can I fix https on my subdoman ?

Hello!
How do I get SSL encryption on my website?
Is this fix via ehcps control panel?

normally, to add ssl support to all your server,
do:
ehcp gui->option->fix apache config with ssl

this makes ssl enabled for all websites, but I am not sure if that is same for mail.domain.com, i am not sure.

Also know that: switching to ssl is sometimes dangerous, may break some configs in your apache, your ehcp may become unavailable, and you may require some manual fixes.
