If you are using email supplied by me (through IONOS) please see the below statement.
As previously announced, we are disabling TLS 1.0 and TLS 1.1 as well as unencrypted access to our email servers. If you have already ensured that encryption is enabled in your devices or email programs, and your devices and programs support TLS 1.2 or higher, you do not need to do anything further.
We are in the process of updating the encryption standards of our email servers. If you or your users are currently using third-party email programs such as Microsoft Outlook or the email app on cell phones, we suggest checking to ensure they are updated and use encryption (SSL/TLS) to connect to our email servers.
Previously, we allowed for unencrypted access and the use of the outdated TLS 1.0 and 1.1 encryption protocols. To protect your email communications, these connections to our email servers will no longer be possible on August 9, 2022.
We will no longer be supporting third-party email clients which do not support TLS 1.2 or higher. Also, SSL/TLS must be enabled in the settings of the email clients. Although we understand that a lot of customers are likely already using updated clients with SSL/TLS enabled, we recommend double-checking to be sure.
If you are unsure of which TLS version is supported by your devices or email programs, please check the documentation offered by your email client provider to find out if TLS 1.2 is supported, and if necessary, perform a software update.
