[comp.mail.uucp] who adds the prefix @uunet.uu.net?

pan@panda.Stanford.EDU (Doug Pan) (03/01/91)

A user can send mail to me through uucp but can't reply to my
messages.  The addresses are:

    send:     uunet!panda.stanford.edu!pan@uunet.uu.net
    reply:    uunet!panda.stanford.edu!pan

I assumed that the reply address was taken from the "From:" field that
was constructed by my host (panda).  Should panda have added the
suffix "@uunet.uu.net" or is it the responsibility of the receiving
mailer?  If it's my responsibility, is sendmail.cf the only place I
have to change things?
