Enable TLS on smtp.aa.net.uk: Difference between revisions

TLS stands for Transport Layer Security - it is similar to https web pages in that the data sent between your email program is sent securely. This is good as it prevents local eaves droppers from seeing your data (and even your username/password credentials if sending using authentication) and it helps confirm that the server you are talking to really is our server and not an impostor on 'man-in-the-middle'.
