Postgrey and the power of Greylisting to fight Spam

Sunday, March 13th, 2011

Wow…. Let me just say that I have typically been inundated with junk mail on my primary address. It’s associated with this domain and has been hosted in an older sendmail setup for quite some time (not really by choice, but because that’s what was installed on the old vps.) I’m currently migrating to postfix […]
