To make our email lists more compatible with libraries' email security configurations, we've upgraded our email list software. If you subscribe to any of the discussion lists that RAILS manages or hosts, the main change you'll notice is that the sender's email address is now on the list messages as a "Cc." This allows the messages to be "From" the list's email address (email@example.com) on behalf of the sender.
With our old software, some library email systems were rejecting list messages, because the messages were "From" the sender's address, which didn't match our server domain. Our software upgrade addresses that problem.
