[LINK] MAC addresses on public wifi

[Adrian Chadd]

I think you're asking "email header" versus "IP packet header", right?

Email header? I've not seen it. But it depends if somehow something
like the Geolocation services are enabled.

IP packet header? Only the LAN will see your MAC. But that may not be
strictly the case in IPv6 - your IP -may- contain your MAC. :)
(I hope this isn't widespread if v6 is widely deployed in the future..)
