I'd have to experiment and see what happens if a user does a reply to all in
that case. If it sends to the people in the Reply-To header as well as the
To header then it would work fine.

I didn't realize that crynwr did this, but it makes sense. As an
alternative (and I know that this is somewhat out of your control) it seems
to me that it would make sense for the mailing list software running on
crynwr.com to allow messages in if the Sender: header is a known address,
even if the From: address isn't. Then lugnet could put Sender:
lugnet.robotics@lugnet.com and leave the From alone. This would most
directly reflect what is in the message too... the message is really from a
user, and being sent by lugnet. Sender is a standard header in some updated
version of RFC822 (well, most likely another RFC which adds Sender to the
list of standard headers). Older software would generally call it X-Sender.
I don't see this as a larger spam hole for the lego-robotics list, because a
dedicated spammer could spam the list now by forging a valid From line
(basically doing exactly what you do on lugnet).

I see this as being true when Followup-To is set, but in general it isn't.
If it were set it seems like you'd want the Reply-To to send the message
back to lugnet (as shown in the example below that I have deleted to save
space).

Hmm, perhaps in the case of gatewayed messages going out (i.e., gatewayed out of the lugnet.robotics newsgroup into the lego-robotics mailing list, or out of the lugnet.loc.us.ca.sf newsgroup into the ba-lego mailing list), the Reply-To field (...)
