Sounds like it's only meta-data of emails, not actual content when TLS is used.

  When TLS is used there is no metadata either... server x talked to server y for a while, but what, if anything, happened we know not.

    >When TLS is used there is no metadata either... server x talked to server y for a while, but what, if anything, happened we know not. Quite a bit of metadata really... Client X: IP address Server Y: IP address Client X request: TLS parameters that can be analyzed through TLS fingerprinting Server Y response: Hostnames supported by SNI Server Y response: TLS parameters that can be analyzed thorough TLS fingerprinting
