supposing you don't have access to a POP account for use with Netscape
Mail, and supposing your system, or rather the system of your University
or organization, is not running on a Unix box or an NT box, and is running
something like VMS, or VM.  Depending upon the limitations of the software
of your University, it might not be possible to address that problem like
that, and some mailers, like mine, tend to due very poorly with certain
reply-to headers....

Oh well.
