David,
In Yahoo Groups, I could put a Reply-To: header in the message I sent, and when people replied, it would go to that address.
I thought I knew Y!Groups inside and out, but this is a new one on me.
I don't know if there may be some combinations of settings that prevents this from working, but it has worked for all my old Y! groups for many years.
It may be useful for those with good intentions, but it's a bad thing because it overrides the settings the Owner/Moderator thought he was making when deciding whether responses should be directed to the group or to the author being replied to. And - as one example - imagine engaging (foolishly) in a "candid" discussion about your boss and then have someone set the boss as the "Reply-to:" address.
You too seem to have overlooked that this is an announcement group. Only the admin can send messages to it, and any replies go only to the admin. If the admin chooses to add a Reply-To: for an individual message, this is a good thing, because it saves him/her having to forward all the incoming replies to someone else.
I'm glad Groups.io inserts a "Reply-to:" header that I assume overwrites any "Reply-to:" a sender may insert.
But it doesn't always! Look at the headers.
In the context of discussion groups where the Owner is given a setting to determine reply-to behavior, the Yahoo behavior is "broken." I'd hope Groups.io never considers implementing it.
As I said, this is an announcement group...
David
