I came across an article yesterday about blocking spam with Postfix using blackhole lists. This is something that I haven’t previously set up and I get a decent amount of spam, so I figured it couldn’t hurt. I followed the directions and in the past day and a half that’s in been in place, over 700 spam emails have gotten blocked…not too shabby! :) 173 still got through, so that’s a pretty darn good ratio in my opinion.
