changing sendmail envelope address

[idsouza @ nchgr . nih . gov (Ivor D'Souza)]

Currently all my majordomo replies are going out with the "From" envelope
of "majordom" (the unix owner of the majordomo distribution).  Is there any
way to change the "From" envelope to send E-Mail as "majordomo" instead?

Thanks.
