Perhaps you should try it again on another email from this list, with
I noticed that earlier in this thread the email was sent with a Copy to
the mailing list. That may be the reason why the list address is not
included in the reply.
Current behaviour of my (web) mail client on this message is that
reply-all sends to the list only, and not to Doug. (Which I believe is
also incorrect because there was a reply-to field to Doug. Oh well, at
least it sends to the list).
