Description:
------------
Is should be possible to add an indication that a message has been passed by
the moderators to the subject line, or as a secondary header in the
message itself, or in the footer.
This way those answering the OP will know that they need to add his/her personal address to the reply. Additionally, the OP will know that tthe message has come from an email address which is not registered, which can happen by accident.
It might also make sense to support "add original poster to Reply-to" in these cases.
