I apologise if I came across as rude, I just felt a massive debate had grown from a simple quetion if a tool existed to mentioning some problem that I didn't know what was.

No, but to me saying something doesn't know if something is waiting, then that it stores the connection details with a timestamp, does. We will just have to differ in that opinion.

I know.

I don't really think I said what it was I wanted. I just find my-self frequently being asked by my wife why a password reset mail (as an example), hasn't arrived, and rather than constantly trawling through logs for her, I could have a URL run a script that output the connections not yet white listed for her to see. That would leave me out of the loop.

So have I, and I have never doubted how postgrey works.

And I still don't know what the problem I have mentioned is. All I am saying is that that tool is an after-the-fact and statistics tool.

I read the man page for that tool before I asked here. 

I will see if I can write a tool for what I need.
