Scheduled

Our encryption provider Echoworx will be performing planned maintenance on July 30, 2021, starting at 19:00 UTC, for the duration of 2 hours.

Impact Echoworx will be removing TLS 1.1 and as such will no longer be supported for secure transmission (or receipt) of email. For several years, Echoworx has preferred (and used) TLS 1.2 for all secure communications, but our services would fall-back to 1.1 if the recipient SMTP did not support 1.2. When this change is implemented, TLS 1.2 will be mandatory.

  • Mail flows where TLS is forced will result in a non-delivery failure (NDR) when TLS 1.2 is not achievable.
  • Mail flows that are opportunistic will fall to delivery in the clear if TLS 1.2 is not achievable.

    TLS 1.1 will also no longer be supported when connecting to the EMX web portal or EMG Admin Console via a browser. The only supported browser actively supporting TLS 1.1 is Internet Explorer 11. Any user attempting to access the service via IE 11 will need to enable support for TLS 1.2 in their browser settings.
