Your first question is the exact same as your original question. What is in
the displayed TO and FROM field are not what is in the envelope. 


Here is the header of your post I am responding to minus the processing
server information:


MIME-Version: 1.0

Content-Type: multipart/alternative;

From: "Kern, Tom" <tkern@xxxxxxxxxxx>

List-Unsubscribe: <mailto:$subst('Email.Unsub')>

Reply-To: "[ExchangeList]" <exchangelist@xxxxxxxxxxxxx>


Now, you will notice that it says FROM you TO the ExchangeList. (I have
removed some other lines that indicate processing or formatting but are not
needed for this discussion.) That is what you are seeing in your e-mail
client, as well as I am. However, the following is the information on FROM
and TO from the envelope of that very same message to me:


X-Note: #### Sender is bounce-exchangelist-1663212@xxxxxxxxxxxxx and spool
file is DEED8034500000353.SMD

X-RCPT-TO: <johnlist@xxxxxxxxxxxxxxxxxxx>


Those lines are taken directly from the envelope that the sending e-mail
server (in this case presented to my e-mail server.
(Those lines are added to the message header by the software I use, however
that exact same information will be in the SMTP logs depending on how
logging is configured.)


As for your second question, do you see the last line of the message header
that starts with Reply-To? That determines what happens when you hit reply.
Some lists are configured to reply to the list, some are configured to reply
to the sender. It depends largely on what is the purpose of the list.

oh and as a follow up to this question, out of curiosity, when an email
comes from a mailing list like this, how does a mail server like exchange
know to expand the list and how does it still keep the list in the TO:


Some lists i'm on don't do that and when you hit "reply" you reply to the
sending user instead of the list.

just wondering how that works.

thanks a lot!


this list is really very good, btw.

thanks for all your help
