Hi Michael,

Ok, I did not know that - if it is spammers common practice, then
fine. I just wanted to say that some companies might see greylisting
as maybe "too strong weapon" and that they would welcome anything to
help with whitelisting.

True.

Right, I should have read the documentation more carefully!
But speaking about the documentation - it should be stated there what
actually blacklisting means. Does it mean that instead of 451
temperror the sender receives 550 harderror?

Again, good stuff, greylisting+SPF in one package -> sexy combination!
I can not wait to see DKIM to be implemented as well.
The only disadvantage with DKIM is that you have to receive the whole
message to judge - an that makes it a bit prone to false positives.
But still.
