This is a small tale of my own incompetence which, I hope, others may learn from....
Our domain had been getting a lot of SPAM email over the Christmas holiday and I had initially put it down to seasonal ill will but was surprised at the sheer volume of unmarked email that was getting through. After some testing I found that email weren't failing some ip4r tests when a manual verification showed the senders IP as being listed by at least one blacklist. After a little research (and I have to admit that my faith in Declude faltered a little) I discovered that the mail server local DNS (SimpleDNSPlus) was auto blocking it's own IP address for 60 seconds very few seconds. I hadn't ensured that the auto blocking feature wasn't correctly configured for loopback IP address. SPAM detection rates have now improved significantly.
