Hi,

I want to be able to block whole TLD's from being delivered. For example we do not want to receive any email from anything at .top

How can I block this?

Well, a quick Google search turns up this:
http://serverfault.com/questions/728641 ... in-postfix

Another way would be to use spamassassin to look for the domain and score it really high, this way you could verify that the messages are actually spam.

There are probably other ways to do it. Take your pick.
