Reply-To header not set by a group

Reply-To header not set by a group

Is there a way to make the group set Reply-To header to the group address?
Right now the header is not set, so clicking Reply button on IMAP client creates a new message to the original message sender. However, most commonly use-case scenario, adapted throughout mailing list community, is that reply, sends the response back to the group.

Am I missing some configuration settings here, or this is not yet implemented?
