Let's remember this is a public list. If one wants to do secure
messaging, this is usually to a restricted list of recipients, each with
their own public key, regardless of the encryption or security software.
About having a shared keypair, the key is no more public. And to encrypt
the message to each and every of us, either the sender has all public
keys, or the mail relay has the ability to decrypt the received message,
and re-encrypt it to each and everyone individually on the list.
As for verifying the authenticity of a given email, this means that
everyone has to sign it, and that anyone who wants to verify the
signature of a given message, the recipient needs to have the public key
of the sender, as well as some trust in this public key, beyond just
downloading it from a key server.

Hi
Re: "China-linked attacks on U.S. telecom networks"
Do we want to have a secure messaging solution for this group?
Is there a preferred encrypted messaging solution for personal use?
Tom's Guide has a report that seems useful.

Thanks!
