Graylisting does work.
I know it works. That's why I said I like it because it stops spam. Been
using my own implementation for years.
I think after I turned it on, the botnet plug-in got bored. My stats for it
dropped significantly. So that’s my proof it does adversely affect botnets.
No, that's your proof that it has a positive impact on your incoming
mail stream. It does not prove that it have a significant negative
impact on the botnets.
From what I see, botnets seem to have resources to spare.
A lot of sending bots still hasn't adapted to greylisting.
Bots still tries to send to addresses we have been rejecting for 10 years.
I suspect that If the botnets were short on bandwidth and computer
power, the programmers would have fix those issues a long time ago. And
the simple fact that they still haven't adapted to greylisting indicates
that it's impact is not (so far) big enough to care about.
