I have a BTConnect email address and am developing a small Dot.Net App to send emails to members of a small charity of which I am treasurer. I have set the App up to use the same settings that I used in Windows Live Mail for connecting to BTConnect, but cannot get it to work. Are there any special settings that BTConnect needs? Advice please!
I've provided a link below with the server settings required for any @btconnect.com email accounts. The instructions below are related to setup on Outlook, but the 'Quick Settings' up top are the details that we're after. I believe Windows Live Mail is no longer supported but you should still be able to authenticate with the mail server regardless.
Many thanks for the link. It pointed out that for out-going emails I need to invoke TLS. C# contains a SmtpClient class which allows the developer to set values including whether SSL is to be used, but makes no mention directly of TLS. The class does allow for a 'ClientCertificates' property to be set and this involves an X509Certificates Collection. On looking up X509Certifcates I see that it involves encryption of messages between the user and the Server (BtConnect in my case), and that TLS depends upon such a certificate. It seems that I will have to obtain a certificate from Brithish Telecom or use a different server without needing TLS.
I assume 'Windows Live Mail' and other Client Apps have such a certificate built-in, or a built-in means of obtaining it because, when stting the BtConnect properties in Windows Live Mail, there is no mention of TLS.
