I'd be curious to know if this would work in my setup. I have fetchmail
pull mail from various POP3 mailboxes on external mailservers and
deliver it to postfix. Now if I put the above lines in my postfix
main.cf what would happen? fetchmail would attempt to deliver mail from
blacklisted addresses to postfix, which would then reject it. But would
it end up just remaining in the external POP3 box waiting to be
downloaded by fetchmail again?

Does adding the above three lines to main.cf work with postfix without
the addition of any other packages?

TIA, Darren
