Very many thanks for reply. Herewith screenshot of the result. Your remedy was successful. And I learned a command that may well be of great value in future
Please note that when I successfully reconfigured Postfix, I had little idea of what information to supply to answer the questions but I will study the manuals etc. in my own time and edit as appropriate. For info, currently I read and write emails from the website/Firefox so there is no panic. As regards what happened previously, I got the first screen but there was no way to make a selection or to press OK.
