One other thing just occured to me. It's possible that the new SMTP
server you're connecting to is configured to work only with its own
domain. On Windows, are you connecting to the network any differently,
such as through a VPN?

Also, most services on Ubuntu are configured to connect only through
localhost, unless you change that, so that's why you're seeing so many
instances of "localhost" in /var/log/syslog.
