Unencrypted Email Access Announcement

Modified on Tue, 09 Aug 2022 at 09:50 AM

Beginning August 9, 2022 IONOS Email (@seolibraries.org) Accounts will no longer be able to send or receive email using external clients such as Outlook or Thunderbird that are not using encryption or TLS version prior to 1.2.


Original IONOS Message:


Unencrypted email access and TLS 1.0/1.1 for POP3, IMAP, and SMTP no longer possible

Dear Customers, If you have problems sending or receiving emails through an external email program (i.e. Outlook, Thunderbird, etc.), it could be because you are accessing your email account without encryption or through the outdated encryption protocols TLS 1.0 or TLS 1.1. For security reasons, we now only support the latest TLS 1.2 and TLS 1.3 encryption protocols. For the transmission of emails between your email programs and our email servers to continue to work, they must support TLS 1.2 or higher and encryption (SSL/TLS) must be enabled. Enable encryption (SSL/TLS) in your email programs Tip: With IONOS Webmail, you can always access your emails using the highest security standards!


Please follow these steps recommended by IONOS to migrate your email client to use TLS version 1.2 for IMAP, POP3, and SMTP:


Both unencrypted access and access using the outdated encryption protocols TLS 1.0 and TLS 1.1 no longer meet current security standards. To protect your email communications, these methods of accessing our email servers will no longer be possible starting on August 9th, 2022.

Please make sure that encryption (SSL/TLS) is activated in your devices and/or email programs. We have summarized below how you can adjust the settings for some of the more popular email programs.

In order for the transmission of emails between your devices/programs and our email servers to continue to work after the new requirements are enacted, your devices/programs must support TLS 1.2 or higher.

Programs and Operating Systems That Support TLS 1.2

  • Microsoft Outlook 2016 (only if all Windows and Office updates are installed)
  • Microsoft Outlook 2019
  • Mozilla Thunderbird 52.0 and newer

  • Apple iOS 9 and newer

Please Note

If you use another email program, we recommend that you check with the manufacturer to see whether or not the program supports TLS 1.2 or newer. If the email program you are using does not support TLS 1.2 and newer, you will not be able to use it to connect to our email servers to send and receive messages after August 9, 2022.

Also, please remember that it is important to install security updates regularly.
