How can I make my domain name email accounts more secure with TLS or SSL?

1. how can i make my domain name email accounts to be more secure with TLS or SSL?

i've a domain name hosted with godaddy.com.

when i tried to configure tls or ssl it wasn't worked.

what can i do to allow more secure email accounts with godaddy credit?

i'm using thunderbird 2 for now.

2. i also want to know how to make the the same account ftp hosting to be more secure.

i mean that i want to make some backups to a server. i'm using genie backup manager.

thanks,

You need to purchase an SSL certificate and have it installed on your server.

Enabling SSL without a certificate is pointless.

so tsl cannot work with godaddy hosting?

i can't even make authorization?

anyway. what is actually the procedure of installing these ssl certificates?

Each hosting company has their own procedure, so I would suggest you contact you host (GoDaddy) and they will be more than happy to help you.
