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" :) ChrisA -- https://mail.python.org/mailman/listinfo/python-list
