Either groups.google.com or giganews ignores (drops) messages containing a base64 encoded block of data, such as the one contained in S/MIME signed messages. We had asked to get this resolved [1], but didn't get a response, and it's still broken.
Apparently the following archives correctly include signed messages: http://blog.gmane.org/gmane.comp.mozilla.crypto http://mozilla.6506.n7.nabble.com/Mozilla-Cryptography-f185722.html http://www.mail-archive.com/dev-tech-crypto@lists.mozilla.org/ For example, search the archives for "ECDSA Thunderbird". Only the archives from nabble and mail-archive contain the complete thread for the "ECDSA support in Thunderbird" discussion from February/March, including David Woodhouse's signed message. We shouldn't recommend that people use the google site to read this newsgroup, nor to search for past posts. I've updated the list information page accordingly. In particular, I've changed the link to the list archive to the nabble.com archive, as that one produced the largest set of results in my tests.
