I've removed the screenshot to protect your personal data. The Authentication message means that the sending of tiscali mail requires Authentication by the tiscali email address (the username) and the tiscali password. As well as using the outgoing server smtp.talktalk.net, port 587 and Use TLS/SSL box ticked.
If you saw the message from TalkTalk advising "Our records show that you are still accessing your email using unencrypted email settings..." then the email address receiving that notification has now been limited to webmail only access OR has a stop on sending mail as a last resort action by TalkTalk to stop the use of email connections not secured by TLS 1.2 encryption.
TalkTalk Mail webmail is secure by design when using an up to date Internet browser.

Enter your full TalkTalk Mail email address and password, select Sign in.
A stop on sending is easily resolved by using currently supported email software and secure email settings as shown in the Email Settings guide below.
If your mailbox is limited to webmail only access for both sending and receiving mail, you will be able to get access restored to email apps or email software, including mail collection services, passwords will then re-authenticate, so long as you're ready to use supported email software and secure email settings for all the ways you view emails.
We can advise on device and software compatibility with TLS 1.2 encryption and provide customer setup guides. Just let us know each mail collection service, each device, its operating system and email software including version that are in current use.
For a definitive check of email settings take screenshots of the incoming and outgoing server settings, image edit to obscure the first part of the email address and upload here using the Camera icon (desktop browser) or Picture icon (mobile browser) above this reply area.
When you confirm the secure settings are ready I can request TalkTalk Support to restore full access. TalkTalk Support will respond here and access will be restored usually within a couple of working days.
