Your email client needs to be updated to ensure secure communication
To provide you with the highest level of security for your email communication, we’ll no longer be supporting TLS email encryption security protocol versions 1.0 and 1.1. Updating to a new email client with TLS 1.2 or 1.3 will make sending and receiving emails more secure from hackers and other online threats.
After 28/5/2022, we’ll no longer be supporting emails sent through TLS 1.0 and 1.1. Going forward, you have 3 options:
1.Update your email clients and operating system to the latest versions on your device.
2.Use webmail for your email services.
3.Get the latest version of a free email client service, like Thunderbird, Foxmail
