In order to bring our mail server system in line with the current industry standard, we have had to make several changes to the encryption that our mail-servers are able to use

The Protocols we now reject in SSL and TLS for mail are:
+no_sslv2 +no_sslv3 +no_tlsv1 +no_tlsv1_1 

The SSL/TLS Cipher Suit we are using is:
ECDHE-ECDSA-AES256-GCM-SHA384:ECDHE-RSA-AES256-GCM-SHA384:ECDHE-ECDSA-CHACHA20-POLY1305:ECDHE-RSA-CHACHA20-POLY1305:ECDHE-ECDSA-AES128-GCM-SHA256:ECDHE-RSA-AES128-GCM-SHA256:ECDHE-ECDSA-AES256-SHA384:ECDHE-RSA-AES256-SHA384:ECDHE-ECDSA-AES128-SHA256:ECDHE-RSA-AES128-SHA256


Users of older operating systems, Outlook, or email clients, may suddenly start to have issues with connecting to our mail servers. We apologise for any inconvenience this may have caused and recommend that any user experiencing difficulties update their software to the latest available.

If you are running Windows 7 and have not already installed it during your normal Windows Updates - Microsoft has released a work-round and patch at https://support.microsoft.com/en-us/help/3140245/update-to-enable-tls-1-1-and-tls-1-2-as-a-default-secure-protocols-in

Clients that have upgraded to Windows 10 report that everything works without further configuration, so if you are experiencing problems running an older version of Windows, we strongly recommend that you upgrade to the latest Microsoft platform and software at the earliest opportunity !

Users of the Thunderbird email client (installed on any platform) and Mac email clients have not reported any issues.

If anyone is still experiencing issues after updating to the latest available software, please open a support ticket.
