    Hi Bertie, phill and Justin

    Many thanks

    Hello--

    For that email issue, the latest update set TLS 1.1 as the default, which could affect older mail clients that do not have that option. If anyone puts in a ticket, they can resolve this by creating a file called /var/qmail/control/tlsprotocol and add: TLSv1+

    cat /var/qmail/control/tlsprotocol
    TLSv1+

      I believe I have this figured out

      You need to create the file tlsprotocol (/var/qmail/control) and if you add the following into the new file, you will enable TLSv1 as follows:

      SSH into server

      vi /var/qmail/control/tlsprotocol

      HIGH:MEDIUM:!SSLv2:!ADH:!aNULL:!eNULL:!NULL:!LOW

      Save

      service smtp restart

      Hope that helps a little

      Many thanks

      Test before tlsprotocol added - no TLSv1

      Testing protocols via sockets

      SSLv2 not offered (OK)
      SSLv3 not offered (OK)
      TLS 1 not offered
      TLS 1.1 offered
      TLS 1.2 offered (OK)
      TLS 1.3 not offered

      Test after tlsprotocol added - TLSv1 now available

      Testing protocols via sockets

      SSLv2 not offered (OK)
      SSLv3 not offered (OK)
      TLS 1 offered
      TLS 1.1 offered
      TLS 1.2 offered (OK)
      TLS 1.3 not offered
