The information relates to getting network authentication for non-encrypted mail. What is it exactly that you're trying to do?
The TalkTalk recommended email settings are here: Email settings - IMAP & POP3
Sending authenticated mail encrypted with SSL/TLS using TLS1.2 will work just fine.
Trying to send non-TalkTalk mail via the TalkTalk SMTP server will not work.
