Without coming out a little heavy handed here. But that order, the one
mj1 uses, is the "correct" way to do it. Even though this section is
"Recommeded" I find it easier to explain that is the way the RFC says to
do it.

The following is from RFC-822:
4.4.4. AUTOMATIC USE OF FROM / SENDER / REPLY-TO
For systems which automatically generate address lists for
replies to messages, the following recommendations are made:
o The "Sender" field mailbox should be sent notices of
any problems in transport or delivery of the original
messages. If there is no "Sender" field, then the
"From" field mailbox should be used.
o The "Sender" field mailbox should NEVER be used
automatically, in a recipient's reply message.
o If the "Reply-To" field exists, then the reply should
go to the addresses indicated in that field and not to
the address(es) indicated in the "From" field.
o If there is a "From" field, but no "Reply-To" field,
the reply should be sent to the address(es) indicated
in the "From" field.
Sometimes, a recipient may actually wish to communicate with
the person that initiated the message transfer. In such
cases, it is reasonable to use the "Sender" address.
This recommendation is intended only for automated use of
originator-fields and is not intended to suggest that replies
may not also be sent to other recipients of messages. It is
up to the respective mail-handling programs to decide what
additional facilities will be provided.
