Is it possible to set up an email gateway so that when it recives email
with an attachement it then send an email to a Lotus Notes server
saying:

"you recieved an email with an attachment if you would like to recieve
this email please simply reply to this email if you would not like to
recieve the email in question please discard this email"

What I am trying to do is to create a system where endusers only recieve
emails with attachments when they are expecting them; to try to fend of
viruses sent through email.
