I have totally gone off the deep end…Spam has made me so mad I have gone on a personal goal to cut the Spam on my servers to 0%…realistic, probably not. Die trying…yep that’s me.

Using a combination of configuration options I have made huge inroads to meeting my goal of 0%. Header checks is just one of the options available. One of the reasons that header checks can be so effective is that Postfix allows you to drop mail before you waste server resources on it.
