I have specific senders that I want not just to file them in the Junk Email
folder when i get their messages but I would like to actually send a message
back informing their messages were rejected.
I use a cable Internet provider for my mail.
Any suggestions?
Oh, you thought spammers actually used their own real e-mail address. Uh
huh. You will end up sending your bogus rejections to non-existing domain
(you make your sending mail server waste its resources), to existing domains
but non-existing user accounts (you make the sending and receiving mail
servers waste their resources), or to an innocent that was never involved in
the spamming but the spammer used their e-mail address (you waste the
resources of both sending and receiving mail host plus you afflict the
innocent with your bogus "rejection" which is spam because it was
unsolicitied and you send it out as fast as you get the spam to which you
are ignorant about replying). In the latter case where you afflict
innocents with your rejection spam (aka backscatter), you can be reported to
both your e-mail provider and to public blacklists.
