Using Thunderbird as news reader

I am using Thunderbird to connect to the Embarcadero forums. It doesn't
work out of the box. This could help:

Go to the Server settings.

Server name: forums.embarcadero.com

Connection security: SSL/TLS (the port number is 563).

By default, this does not work since the server at embarcadero
apparently still uses protocol parameters that are (considered as)
vulnerable to the logjam vulnerability
http://arstechnica.com/security/2015/05/https-crippling-attack-threatens-tens-of-thousands-of-web-and-mail-servers/

Thunderbird doesn't accept these parameters anymore (by default), it
says: "SSL Key received a weak ephemeral Diffie-Hellman key in server
exchange handshake".

The "solution" is the following:

In Thunderbird, goto Tools/Options/Advanced/Config editor...

Say "I'll be careful, I promise!"

Then search for "security.ssl3.dhe_rsa_aes", and double click on both
entries (128 and 256) so that they become both false.

Maybe Embarcadero should also upgrade their server security parameters...

Thank you. Now my Thunderbird works!

By the way, is there a detailed explanation of how to compile XanaNews?
I've been away from programming Delphi for quite a while, and it is
not immediately apparent how to do this, using the download from:
https://github.com/graemeg/xananews

I have XE7 and used the XanaNewsGroup_DXE5.groupproj file, but found I
had to open the various component projects separately, and compile them.
Still,that didn't seem to work, and I got errors when trying to
compile the "big" program.

Thanks
David Keith

Thanks! That fixed it for me! Thought it was a matter of the server being down again. Awesome!

Thanks! That fixed it for me as well. Of course I'd like EMBT to add these required crypto standards to their server.
