When you send email, you have to have a valid envelope-from address,
which can be found in the headers. But the From: address doesn't
technically have to be valid. And if the email you received actually
came from the news<->mail gateway, then it's even less significant;
the address used is simply whatever Grant chose to key into his
newsreader, which in this case is a marker saying "Please don't email
me, just follow-up to the group" :)
