Thank you for the heads-up,

Depending on what the sender's local address is substituted with, this could be great if it is just truncated or dumb if it is substituted with something like "localhost."
Also, for business E-Mail you may not want it truncated or substituted. If your domain name is part of your so-called "brand identity," you'd probably want it to show in the first "Received" header.
I suppose that if your business is big enough, you'd probably run your own mail server.
Just my two shekels.
