I have a question about email security (between user and email server) - about the content, and difference between "STARTTLS" and "SSL/TLS", the options Thunderbird gives for connection security.
In a way, the question would be Super User material, since it discusses the options of a specific end-user software - Thunderbird. However, in another way the question would be IT security since on a deeper level it really is about understanding methods of securing email connections.
So, does this sort of question belong to Super User or here in IT Security?
(*sigh* I'm finding this division between non-pro / pro really confusing...)
