I receive a majority of my e-mails from one sender. Can they automatically
be
moved to a folder on my desktop or a folder on one of my harddrives?
I assume that your intent is to separate mail from that sender from other
mail. You don't say what E-mail client you use, but most E-mail clients let
you create separate folders and write a rule to move particular classes of
messages to those folders as desired. That technique effectively makes
multiple inboxes for you, and automatically sorts mail to the appropriate
inbox as it arrives That's probably the easiest thing for you to do to
accomplish what you want.
Moreover , if your E-mail client doesn't have that capability, in my view
that should be grounds for changing E-mail clients. To me that capability is
a very useful and important one.
