Subject: Gmail complaining about authenticity of emails sent/received via

Hi All,

I'm using gmail.com for corresponding to this mailing list.

Recently I have observed that gmail has started complaining about the
authenticity of the sender.

Eg: I see this message quite often when someone replies to a kernewbies post:

This message may not have been sent by: xyz at gmail.com

Is anyone else seeing this too?

I think mailing lists set a "via" (or some such) header in the mail to
indicate that the mail is being sent on behalf of the original sender.
Could that be missing?
